Monica and Chandler's relationship was much, much better than Ross and Rachel's on Friends, but it wasn't perfect. It had its problems, though there were no issues when it came to their love story, unlike like Ross and Rachel's relationship. However, some things just didn't make sense.

There were a more than a few problems about their relationship. There were some things that Monica and Chandler should have known about each other and didn't. In at least one case, this was because the writers had obviously not decided on their backstory — or that they would even get together — yet. This was one of the main issues, as well: the relationship was never actually planned.

In other cases, the issues were as simple as playing something for laughs without thinking about the characters. There were some things they should have known about each other once they were together, engaged, or married. There was also the matter of the series being a comedy and all of the relationship drama coming from Ross and Rachel. Because of this, most serious situations involving Monica and Chandler were resolved quite quickly. In fact, they didn't have many conversations that they should have had on-screen.

The way they treated their exes, such as Richard and Janice, was strange as well. Sometimes they were jealous, while other times, they acted like the moments that the other shared with them didn't matter.

Here are the 20 Things About Chandler And Monica's Relationship On Friends That Make No Sense.

Chandler's Surprise at Monica's Weight

In season 2, the gang saw what Monica and Rachel looked like the night of their prom. Monica's weight at the time surprised those who didn't know her then. She tried to defend herself by saying the camera added 10 pounds. "How many cameras were on you?" Chandler asked. However, her weight shouldn't have surprised to Chandler.

In the season 5 episode "TOW All the Thanksgivings" we can see that Chandler met Monica when she was still overweight.

He even commented on it in that flashback. He visited the Gellers for the November holiday again and saw her after she lost the weight as well. A simple explanation is that the writers hadn't yet decided on Monica and Chandler's history. However, it's still a glaring error in their story.

Chauncey

Friends Jack Chandler

After Monica and Chandler got engaged, he decided to try to get to know her father. According to Ross, Jack referred to Chandler as "Chauncey" in the season 7 episode,"TOW Phoebe's Cookies". This was obviously only for laughs, as Jack should have known his name.

Chandler visited the Gellers' home multiple times when he was Ross' roommate in college. One such visit included Monica accidentally dropping a knife on his foot, causing him to lose his toe. They accidentally left the toe in the kitchen and brought a carrot to the hospital. Wouldn't he remember the guy whose toe was in his house? Also, Monica's parents already visited their apartment after Chandler moved in. How could he not remember the name of the person in a long-term relationship with his daughter?

Chandler and Richard Slipping People Money

In season 2, Joey and Chandler tried to be friends with Richard when he and Monica dated. While they spent time with him, he taught them how to slip people money. This didn't last long, though, since they compared him to their fathers because of the age difference.

However, in season 7, it was like this never happened. Chandler tried and failed to slip a host money to get him and Monica a table at a restaurant. He asked if Richard had ever successfully slipped someone money. However, he knew that Richard was good at the skill. Considering how insecure Chandler was about Monica's relationship with Richard, it's surprising that he didn't remember this detail.

Chandler's Ignored "I Love You"

In season 5 episode "TOW All the Thanksgivings", Monica put a turkey on her head. It was part of her apology for accidentally causing Chandler to lose his toe years ago. He'd called her fat, so she'd tried to get back at him after she lost weight. She tried to flirt, using items around her, including a knife.

After he found out about this, she apologized and danced around with the turkey on her head. She even added a fez and giant sunglasses to the turkey. When she won him over, he said, "You are so great. I love you." However, he pretended he didn't say it. While she was arguing that he did, Joey showed up and the scene ended. Neither mentioned it again. Six episodes later, they both said it and acted like this was the first time.

Monica Didn't Know What Chandler's Job Was

It was an ongoing joke for the entire group that no one knew what Chandler did.

In the season 4 episode "TOW the Embryos", Monica and Rachel admited that they had no idea what his job was, despite the fact that they were all friends for years already.

Later in the series, Chandler quit his job after he briefly transferred to the Tulsa office. This meant a career change for him, though it also meant that he and Monica made less money for the time being. He suggested that he get his old job back, and she told him she wanted him to have a job he loved, "not statistical analysis and data reconfiguration." He then replied: "I quit, and you learn what I do?" Yes, it was just a joke, but they were together for years and married at that point.

Monica Didn't Care That Janice Thought Chandler Had Feelings for Her

Chandler and Janice in Friends

The way Friends treated Chandler's relationship with Janice is a headscratcher. He loved her when they were together and even wanted her to leave her husband for him. However, once she was out of his life, he couldn't get far enough away (say, to Yemen). Janice popped up several times after Monica and Chandler got together. More than once, Monica was okay with her thinking that Chandler had feelings for her to get rid of her.

First, it was so that she wouldn't attend their wedding. Then, it was so that she wouldn't move into the house next to the one they were buying. Janice even kissed Chandler at one point. However, Monica basically waved it off. The show treated it like a joke. Why didn't they ever have a serious conversation about this?

They Barely Talked About Monica Not Going to Tulsa

One day at work, Chandler fell asleep during a meeting after staying up all night worrying about it. Because of this, he unknowingly agreed to move to Tulsa and couldn't get out of it. At first, Monica planned to go with him. However, when she received a job offer in the city, she decided to stay. Their conversation was too brief for the seriousness of the situation.

She joked about how they'd be too busy to see each other for most of the week anyway. He accepted her decision easily. However, this wasn't the problem. It was right that he wanted her to take a job she wanted, but it wasn't until he was leaving for Tulsa, in the hallway outside their apartment, that they really spoke. She told him that he was more important than a job, but she that had to take it.

Monica Forgot How Important Humor Was to Chandler

Chandler's humor was always important to him. For example, he couldn't even sleep when he and Ross argued over ownership of a joke printed in a magazine. Though Monica was thinking about her own problems at the time, she still spoke to him about it. She was even the one to determine that neither of them should want to be the joke-teller because it was rude.

Then, while Chandler was living in Tulsa, Monica started a job at a new restaurant. She told him all about the place, saying that one of her coworkers was the funniest guy she'd ever met. Ross and Joey had to clue her in on why this bothered Chandler so much. However, Monica should've already known that making jokes was so important to Chandler.

Richard's Forgotten Appearance Before the Proposal

Since the others knew that Chandler was doing to propose to Monica, they asked to see Monica's hand when she and Chandler got home. Chandler hadn't asked her yet, though, and was instead worried that she was suspicious. He decided to make her think that marriage was the last thing on his mind.

Richard then showed up at her work and asked her to marry him.

She even went to his apartment before finding out Chandler's plan, and Chandler later found out about this. Yet, once they both proposed, they acted like Richard had never come back. Why didn't they ever talk about Richard's proposal or Monica taking time to think after it?

Monica Didn't Care That Chandler Ran Off

Chandler's fear of commitment kicked in when Monica referred to them as "the Bings" on their answering machine. He ran off the night before their wedding, and Ross and Phoebe found him later in his office. Phoebe alerted Rachel that they'd found him before she told Monica that he was missing.

Then they thought that Chandler ran off again before the wedding. They believed that Monica was pregnant and Chandler was scared. Again, they didn't tell Monica. However, no one told Joey not to tell the bride, so he clued her in during the ceremony. Chandler's vows were sweet, but Monica basically waved off the fact that he almost ran out of her.

The Valentine's Day Mixtape

In the season 6's  episode "TOW Unagi", Monica and Chandler decided to make each other Valentine's Day gifts. She gave him a sock bunny, which Phoebe had actually made. He, in turn, ran around, asked others for help and grabbed a mixtape that he found lying around.

He didn't even bother listening to it first. After he called her out on not making her gift, they didn't listen to the mixtape for a day. Instead, he listened to it for the first time beside her. Suddenly, they both heard Janice's voice on the tape. Like most things regarding Janice, Monica just let it go. However, it's a bit weird to still have a mixtape from your ex lying around.

Kissing Another Woman and Opening Gifts Made Them "Even"

In "TOW the Red Sweater", Chandler couldn't find the cameras from his and Monica's wedding reception. So he and Ross tried to recreate some key moments from the event, including the kiss with the bride. They crashed another wedding's reception, and Chandler kissed another woman. Meanwhile, Monica couldn't resist opening her and Chandler's wedding gifts, even though she just started with one small one.

When the newlyweds met up, Monica revealed that she found the cameras. This meant the photo she held was evidence of him kissing another woman. Then Chandler saw the open presents. He asked if they could "call it even" and she agreed. However, how is kissing another woman and opening gifts anywhere near the same?

The Confusion About Monica's Belief in Soulmates

During her vows, Monica told Chandler that he was everything she'd been looking for when she needed comfort in London. She called him her "prince" and "soulmate."Not even a year after their wedding, Phoebe thought that she was dating Monica's soulmate. Chandler was worried, even though he admitted that he didn't believe in soulmates.

Monica then told him she didn't believe in soulmates either and that she didn't think they were destined to end up together.

They fell in love and worked hard at their relationship. While that was true, it negated what she told him during their wedding vows. Neither of them seemed to remember this, though, which they should have. After all, their vows were personal and romantic.

It Wasn't Planned — Even After London

Chandler and Monica from Friends

The chemistry was pretty much always there between Courtney Cox and Matthew Perry. They were the perfect example of "friends who became more." However, at the beginning of Friends, it was all about Rachel and Ross — and everyone else's minor relationships. It wasn't until season 3 that the writers considered putting Monica and Chandler together. "It was too early to explore" then, former executive producer Scott Silveri told Vulture.

The EP also revealed that it was uncertain if Monica and Chandler's relationship would last after London. It would have been a mistake if it hadn't happened. Monica and Chandler's relationship was so much better than Ross and Rachel's. It was smart to be cautious about their relationship. However, it's crazy to think there was ever a question mark once that hookup happened.

Their Wedding Venue

Monica, Rachel, and Phoebe were at a museum when they overheard someone showing it as potential wedding venue. The other women talked Monica into putting her name on the registry, just in case. A woman from the museum called and left a message about the venue soon after. Chandler overheard and promptly freaked out. Monica assured him that she didn't think they'd be getting married. Then, viewers found out that he had planned to propose and keep the venue.

After they got engaged, Monica took out the wedding binder from her childhood. Yet, the series never really showed them planning the wedding outside of this and big things like her dress and their vows. They never went to look at venues and they never mentioned that museum again. In fact, it looked like they got married in a hotel.

Chandler Turning to Ross and Joey for Advice & Proposing Because He Was "Sorry"

Friends Chandler first proposal

Though Monica and Chandler got together after their time together in London, they kept their relationship secret. However, gradually, the others found out. Once everyone knew, their friends started talking about their future. What would they get them for wedding gifts? Who would be their babies' godparents?

Chandler promptly began panicking, and he and Monica fought about it. As she pointed out, she never said that she wanted those things in their relationship right away. Chandler then turned to Ross and Joey for advice, which led to him proposing. They even addressed why this was such a bad idea - Ross had two divorces to his name at that point and Joey preferred casual dating. Yet, the show had it go far enough that Chandler actually proposed — and told Monica that he was doing so because he was sorry.

The European Kissing

When Monica and Chandler first got together, they kept it from the others, which meant that they were sneaking around and hiding when they were together in romantic situations. However, they slipped up early on. Chandler was heading off to work, and he kissed Monica goodbye. She kissed him back and didn't seem surprised by it.

Yet, when they realized that others were present, they pretended that it was some European thing that Chandler had picked up in London.

The others bought it, even after they walked in on Monica and Chandler kissing alone in her apartment. Plus, Monica didn't even care that Chandler kissed Phoebe and Rachel each time the others saw them.

Monica Didn't Know Chandler's Glasses Were New

It was an ongoing joke that the rest of the group didn't know certain things about Chandler. They didn’t know what his job was. (Even Monica didn't know until after he quit, in season 9, four years after they got together.) Then, in the season 7 episode "TOW Phoebe's Cookies", Chandler showed up wearing glasses one day and the others thought he'd had them the entire time.

Monica, his fiancée, also thought that he'd always worn glasses. They'd been together two years by that point, living together for a year and friends for much longer. It was one thing for the others not to know, but to have Monica act like she thought he'd had glasses this entire time? It just didn't make sense.

Monica and Chandler's Off-Screen Talk About London

Monica went to Chandler's room while everyone was in London for Ross and Emily's wedding. She was sad after someone mistook her for Ross' mother. Also, her brother was getting married and she didn't have any prospects. After the two spent the night together, they said it would only happen in London. However, this didn't last once they returned home.

It wasn't until after their engagement that the truth about London came out. Monica was really looking for Joey because she just wanted some comfort and nothing serious. Chandler was hurt, and he walked out of their apartment. He then spoke with Joey and agreed to let him officiate their wedding. However, Monica and Chandler talked off-screen. After, they informed their friends that they'd talked and everything was alright.

Monica's Secret Closet

In season 8, Chandler found out that Monica had a secret, locked closet in their apartment. He then tried to break into it and soon discovered that it was a complete mess. However, Chandler had been living in the apartment for two years by this point, so it shouldn't have been a secret. He'd been friends with Monica and had even lived next door for years before that.

Rachel also lived with Monica in the apartment for multiple years. Someone should have known about it before this point - or Chandler should have at least asked about it. It would have at least made some sense if he'd discovered it while he was moving in, two years earlier.
