The fourth season of How I Met Your Mother was a total rollercoaster. It roundabout marked the halfway point of the series, which meant quite a bit of character development, but not too much to make audiences feel like they got everything they could from it. Ted almost got married, and then was left at the altar, Robin finally finds out Barney is in love with her, and Marshall and Lily are closer to adulthood every day that passes.

But all of the things fans love most about the show remained present. The running gags, the personality traits that define each of the main characters, nights spent at the bar drinking booze and talking about the most random things, all of that was still there. If it's been a while since the last time you got to experience a little bit of How I Met Your Mother, take a stroll down memory lane and revisit some of the best and most hilarious moments from its fourth season.

The Possimpible (8.4)

By the time "The Possimpible" rolls around, Robin has been out of job for some time. Once she finds out she has seven days to find work or she'll be deported, she takes up Barney's offer to create a video CV for her...that has nothing to do with expertise.

Meantime, Marshall, Ted, and Lily consider cleaning up their resumés and remove things like "Hot Dog Eating Champion" from the list. Everyone's been there at some point in their lives!

Murtaugh (8.5)

It comes a time in everyone's lives where they realize they're simply too old for some things. And this particular episode is all about that! After Barney is kicked out of his laser-tag club, Ted reveals to him that he has a list filled of things he's simply too old to do, prompting Barney to take on the challenge of doing them all.

Some of these things include going to a rave, sleeping on a friend's couch, piercing his ear, and a myriad of other crazy things. Ted goes on the complete opposite direction and does things worthy of a retired old man. The outfits alone make this episode worth while!

The Best Burguer In New York (8.5)

Early on in the season, Marshall is unemployed and struggling to even put on pants in the morning. This leads to him putting meaning in weird things, the most prominent one being the search for a burger joint where he claims to have had the best burger of his life. The whole gang goes on to search for the mythical place.

Eventually, they found it, and Marshall ends up admitting to Lily that he will put his dream to become an environmental lawyer on hold so he can work for Barney's company. Now, he at least has a reason to put on pants!

Three Days of Snow (8.5)

Adorable as they are, Lily and Marshall have a tradition every time he picks her up from the airport. But now that they are facing a blizzard of historical proportions, they struggle to uphold tradition.

On the other hand, Barney and Ted have the chance to run a bar during said blizzard. It's always been their dream to buy a bar together, and as much as they love it at first, it ends up being a complete disaster.

Benefits (8.6)

Now that Robin and Ted are roommates again, they're constantly fighting over minimal things. However, they eventually discover that sleeping with each other can solve most of these conflicts, which makes Barney insanely angry, prompting him to come to the apartment and try to solve things by himself due to his love for Robin.

In the meantime, Marshall reveals he is too shy to use the bathroom at work, which leads to a series of hilarious moments and even a cameo by influencer and star Kim Kardashian.

Do I Know You? (8.6)

The first episode of season four opens exactly where the previous season left off, with Ted proposing to Stella. Pretty much right off the bat, Stella accepts his proposal, and the two spend the summer happily engaged. However, Marshall helps Ted realize that he doesn't really know much about the person he is about to spend the rest of his life with.

On Barney's side, he finally admits to Lily that he's crazy in love with Robin, prompting Lily to try and change Barney's ways of sleeping around and refusing to show emotion.

The Three Days Rule (8.7)

When Ted meets a woman he likes and gets her phone number, Barney is quick to explain to him about the three-day rule, which states that one must wait at least three days to text someone you just met.

Ted, of course, doesn't comply and goes on a texting spree with the woman. Little does he know, the people texting him are actually Barney and Marshall, and things get really weird, really fast.

The Leap (8.8)

Ted's thirty-first birthday is fast approaching, and he's at a crossroads in his life. He doesn't want to accept the job offered to him as an architecture professor since he perceives that as a failure. And this prompts him to accept the only project offered to him, designing a restaurant shaped like a cowboy hat.

Being the last episode of the season, it would obviously come with plenty of action and surprising moments. A goat wrecks havoc on Ted's party and Barney is ready to tell Robin he has deep feelings for him.

Intervention (8.8)

One of the funniest gags around the show was the intervention. And this is the episode in which the show finally introduces it, as the gang decides to stage an intervention every time a member of the group does something to bother the other. In the meantime, Barney is set to prove he can pick up a woman posing as an 80-year-old man.

The Naked Man (9.2)

Once the gang finds out a strange move called "The Naked Man" actually worked on Robin, both Ted and Barney take it upon themselves to attempt the play. It worked on Robin, but will it end up working for Ted, who's trying to move on from Stella, and Barney, who's...well, Barney?
