Comedy TV shows tend to fall into two basic camps. Many aim to be family-friendly fare like Full House, never diving too deeply into any heavy or potentially inappropriate subject matters and always keeping their jokes light and innocent.

Others, like Friends, hide a shocking amount of inappropriate and sometimes downright controversial humor behind their catchy jokes.

As it turns out, there are often just as many wild and crazy times behind-the-scenes as there are onscreen. Even some of the more subdued and PG television shows can be host to spontaneous parties and hilarious drama.

Some sitcom stars, like Big Bang Theory's Johnny Galecki and Kaley Cuoco, get super risqué with their clothing choices.

While others, like Fuller House's Lori Loughlin, get a little handsy with their co-stars (and, no, we don't mean John Stamos, surprisingly).

From Beth Behrs' impromptu bar dance on the set of 2 Broke Girls to celebrating on Friends, here are the 15 Wild Behind-The-Scenes Photos Of Amazing Sitcoms.

Lori Loughlin Gets Touchy-Feely On The Fuller House Set

There have always been wild and scandalous rumors about the cast of Full House.

From the parents of the little Tanner ladies storming the set to complain about Bob Saget, John Stamos, and Dave Coulier's raunchy humor behind-the-scenes to the drama of trying (and failing) to get the Olsen twins to sign on to the Fuller House reboot, this cast never fails to entertain with their behind-the-scenes antics.

Naturally, the cast gathered together for some wet and wild fun when they reunited for Netflix's reboot.

Despite Becky's responsible sweetness, actress Lori Loughlin has often been described as outgoing and hilarious.

Here she shows off her spontaneity by getting up close and personal with Coulier at the cast pool party. He seems to be along for the ride, holding his shirt out of the way to provide the goofy photo op.

Buster Bluth Gets Patriotic On The Arrested Development Set

Buster Bluth is known to be socially awkward. From his uncomfortable shoulder rubs and unfortunate panic attacks, the guy really had his work cut out for him in a series filled with awkwardly unique characters.

Expertly portrayed by comedian Anthony Hale, Buster never fails to steal whatever scene he happens to be in.

Buster joined the Army after being dared by his mother, but was excused from service when a seal bit his hand off while he swam in the ocean before going off to war.

In this photo we see Hale showing his respect to the armed forces. Except Hale's backward bending stance, frightened facial expression, and bizarre wardrobe makes an inspiring photo op totally hilarious. Hale's blue coat and total lack of pants take everything over the top.

Beth Behrs Got Wild On The Set Of 2 Broke Girls

Between the two main characters of 2 Broke Girls, Max was certainly the crazier of the two. She was wild, crass, and totally unapologetic.

Her roommate and co-worker, Caroline, was classy, proper, and kind of snooty. It turns out, Caroline actress Beth Behrs had a talent her onscreen counterpart did not: the ability to let loose.

In this photo, Behrs shows off her Coyote Ugly style dance moves, getting jiggy with it on the bar of the diner the girls worked at. Behrs really got into her performance, seemingly getting carried away with the moment.

Behrs' co-star, Kat Dennings, does not appear to be affected by Behr's wild performance one way or another. This was just another day at the office for this spontaneous crew.

The Ladies Of Jane The Virgin Compare Baby Bumps

In 2015, Jane the Virgin's Justin Baldoni was expecting two babies. His wife, Emily Baldoni, was pregnant with the couple's first child.

While Baldoni's Jane the Virgin character, Rafael Solano, was accidentally expecting a baby with his employee, Jane Villanueva, on the show at the same time.

Baldoni posted a photo joking that it was better to have two "Baby Mamas" and referenced the fact that life imitates art.

In the photo, Baldoni's pregnant wife shows off her real baby bump for the camera. Jane actress, Gina Rodrguez, joined in on the fun by showing off her fake pregnant belly alongside Baldoni.

Jane stayed true to the show's premise, keeping her promise to remain celibate but became pregnant by accident through an OB/GYN mishap.

Emma's First Birthday On The Friends Set

Fans of NBC's Friends are often split over who they believe Rachel Green should have ended up with in the end.

Was she better suited to Ross Gellar? Or had Joey Tribbiani proven himself a worthy option? Or should she have gone off to Paris by herself? (That last one is the right one, to be honest.)

Well, whether we like it or not, Rachel ended up with Ross and the two had an adorable little baby, Emma Gellar-Greene.

This sweet photo features Courtney Cox, Jennifer Aniston, and Lisa Kudrow celebrating Emma's fictional first birthday. The room is festooned with balloons and presents, while baby Emma is all decked out in her fancy white dress.

Emma was played by twin sisters Cali and Noelle Sheldon. The girls naturally can't remember much of their time on the show, but they enjoy the photos that came out of that time.

Clowning Around On The Two And A Half Men Set

Jon Cryer was quite vocal about the problems Charlie Sheen presented on the set of Two and a Half Men. When some sided with Sheen when he was fired from the show, Cryer tried to set the record straight with his own version of events.

Between substances, street workers, and never showing up to work on time, Sheen put a serious delay in filming on more than occasion, according to his co-star.

When Ashton Kutcher replaced Sheen in season 11, he proved he could be a distraction on set too.

Here Kutcher can be seen playfully roughhousing with his co-star on set. Looks like Kutcher's spontaneous charm really swept Cryer off of his feet.

Cryer doesn't exactly look like he's comfortable here, but he has to have been preferable to hiding Sheen's stash when his wife showed up to set... so, there's that.

Sofia Vergara's (Fake) Pregnancy On The Modern Family Set

Sofia Vergara has always been very proud and happy about her time on ABC's Modern Family. She's described the experience as a party and gets her family to come along with her when the show is nominated for awards.

Vergara loves being a mom too. She also credited her husband, Joe Manganiello, with helping her to be able to achieve her goals while being a single mom.

What Vergara didn't love, though, was wearing the fake belly in order to portray Gloria Pritchett's pregnancy on the show.

Vergara admitted that the fake belly made her feel hot and uncomfortable and kept her from being able to bend over. No wonder she seems so triumphantly excited about co-star Julie Bowen giving this big, fake a belly a solid kick.

Neil Patrick Harris Suits Down On The How I Met Your Mother Set

Barney Stinson became well-known for his bad treatment of women, his zany and elaborate schemes, his surprisingly caring attitude toward his friends (he basically got Lily and Marshall back together), and of course, his impeccable and expensive wardrobe.

No matter what the circumstances were, Barney made sure he was always dressed to the nines, even his pajamas were suits.

Nothing may suit Barney Stinson like a suit... but Neil Patrick Harris makes very different fashion choices at times.

In this photo, Harris can be seen embracing someone on the set of NBC's How I Met Your Mother. In true, hilarious Harris fashion, he decided to go sans pants for the occasion.

Harris was definitely suiting down as compared to his character's typically suave and sophisticated wardrobe.

The Cast Of Brooklyn Nine-Nine Knows How To Have Fun

The set of Brooklyn Nine-Nine seems like an absolute blast. From lego kits to Barbie dreamhouses, the set is constantly filled with silly items designed for whimsical, childlike fun.

When it comes to the cast of Brooklyn Nine-Nine, it's go big or go home. These guys really know how to have a good time in spades.

In this photo, Melissa Fumero, Stephanie Beatriz, and Terry Crews get up to some fun in a huge bounce house behind-the-scenes.

Crews has gained media attention for being part of the #MeToo and #TimesUp movement. The former football player and comedian has been very vocal about the state of the entertainment industry for not just women but men as well.

It's great to see Crews smiling and having a great time with his co-stars.

Debra Messing Shows Off A Fixer-Upper On The Will And Grace Set

The Roseanne reboot has shown the world that reboots aren't gone. Viewers may become frustrated with what they believe to be Hollywood's unoriginality but with the smash success and insane ratings the blue-collar show has proven there is still a market for nostalgia.

The reboot isn't ruined if done properly, apparently.

However, before Roseanne smacked it out of the park, Will And Grace earned respectable buzz and a second season thanks to its powerhouse cast of comedians and biting sarcasm.

Here Grace Adler actress, Debra Messing, shows off a serious fixer-up on set. She's all smiles in this photo, but these walls could definitely use a little work.

The walls are torn and big, gaping holes can be seen, but Messing didn't let that hold down her happy spirit.

John Goodman And Roseanne Barr Take A Nap On The Roseanne Set

The Roseanne reboot is basically making history as we speak.

It has seemingly revitalized network TV, boasting a noteworthy debut that caused Darlene Conner Healey actress Sarah Gilbert to proclaim that network television is not gone yet and prompting President Donald Trump to call Roseanne Barr to congratulate her on her show's success.

Living up to all that hype has to be exhausting, so it just makes sense that Barr and co-star John Goodman would need to take a break every now and then.

In this sweet photo, Barr and Goodman snuggle up to each other for a quick snooze between reading their scripts on the show's infamous striped sofa.

At least there's a blanket close at hand, these guys should just go full cozy.

Chris Pratt Got In Shape For Marvel On The Parks And Rec Set

Chris Pratt is an expert multitasker. He can easily star in a beloved hit comedy series and save the world from rogue dinosaurs and Ronan the Accuser at the same time.

Oh, and he could ad lib hilarious one-liners and get himself in MCU shape simultaneously while on the set of NBC's Parks and Recreation.

Pratt famously got in shape for his role of Peter Quill in Marvel's Guardians of the Galaxy. He posted photos of himself hitting up the gym and shared his strict diet on the interview circuit.

Being on set didn't give Pratt a break from his new lifestyle. In this photo, Pratt drops and gives the camera twenty while taking a break from filming while a couple brave crew members join in.

There Were Stairs The Whole Time

Charlie Kelly is always getting up to crazy hijinks in It's Always Sunny in Philadelphia. One minute he could be scaring off dates with his milk steak obsession.

The next he could be squaring off against the dastardly McPoyles. No matter what kind of antics Charlie got up to, they were sure to be totally weird.

In season 6 episode 5 "Mac and Charlie: White Trash", Charlie and his friend Mac attempt to fix up an abandoned pool during an intense heat wave.

The friends get stuck in the bottom of the trash-filled pool and spend hours thinking up ways to get back out. In this photo, Day takes a much-needed break while a conveniently placed flight of stairs can clearly be seen in the background.

Steve Gets Close To The Demodog On The Stranger Things Set

Season 1 Steve Harrington had Stranger Things fans on the fence. Some hated him for his treatment of Nancy Wheeler when he thought she was cheating on him with Jonathan Byers.

Others loved the fact that he owned up to his mistakes and attempted to mend the hurt he had caused.

Steve has only begun to grow in the audiences' heart. His reformed ways and "cool dad" persona made him a stand-out fan favorite in season 2.

Steve actor Joe Keery has proven to be just as lovable behind-the-scenes.

Whether he's professing his love and admiration for Stranger Things co-star Gaten Matarazzo or sharing his proud photos of himself with his multiple babies (here its the scary Demodog Queen), Keery has almost overshadowed his popular character by being his own lovable self.

Stuff Went Down On The Big Bang Theory Set

The characters of The Big Bang Theory are known to be rather averse to normal human interaction. Sheldon Cooper won't even give out hugs most of the time.

However, the actors behind-the-scenes weren't afraid to get a little... rowdy from time to time.

Penny and Leonard donned some rather risque clothing in an episode in which Sheldon had a nightmare that his friends had begun using his room to act out some shocking fantasies.

While the scene was meant to be uncomfortable for the characters, actors Johnny Galecki and Kaley Cuoco, who were exes at the time the scene was filmed, had an absolute blast in their black leather gear behind-the-scenes.

Good thing Galecki kept Leonard's glasses close at hand.
