Some of the ones with Monica

The one where Monica cleans her apartment.

Monica decides to throw a small party at her apartment. Beforehand, she wants to give it a deep clean to make it more presentable. She gets in the mood, puts on rubber gloves, and turns on the radio while she starts to scrub the place. While doing so, her clothes get dirty. Since she doesn’t want to do laundry before the party, Monica decides that it’s better to clean au natural.

Before she knows it, the rest of the gang and guests arrive. Monica had become so absorbed in her task that she lost track of time. All the guests find a naked Monica, sans gloves, dusting the shelves while rocking her head up and down to a song.

Joey can’t help but say “nice” while some of the other guests laugh, and Monica realizes she has company. She shrieks and runs to hide in her room, tripping over the couch on the way there. The episode ends with a freeze-frame of Monica’s ass high in the air, all of her friends and acquaintances gasping.

The one where Monica gets locked out.

The workers at Alessandro’s are still mad at Monica for getting the previous chef fired, so they keep bulling her. They intentionally burn her chef jacket, write mean things on her hat, and accidentally spill tomato sauce on her body.

Monica tries to go for a shower and change at the end of the shift, but the other staff take away their clothes and cut the power before faking a fire alarm. Wet and naked, Monica stumbles out in the dark. She trips, slides, and crashes into quite a few things before reaching the backdoor.

As soon as she sets one foot outside, the door closes behind her, locking shut. Her coworkers are there to laugh at her and take a few pictures. Monica screams and scrambles to cover herself, but she refuses to touch anything in the dirty alley, so she half-crouches to cover up. She meekly asks the staff to give her clothes back with a timid smile, but they just leave her there.

The rest of the episode includes quick cutaways where Monica streaks from alleyway to alleyway, apologizing to any bystanders she runs across and squealing whenever a car passes by as she braves the crowded New York streets in the nude.

The one where Monica pretends to be an exhibitionist.

Monica and Chandler are seeing each other in secret and having romantic escapades. They accidentally leave behind lewd photos and used underwear. When the other friends find all of this, Joey takes the heat so that the relationship between Monica and Chandler can remain a secret.

However, it all ends when the rest of the gang finds a naked video that Monica left for Chandler. Rachel accuses Joey of recording the video in secret and being a creepy stalker, but Joey has had enough. He reveals that it was all Monica’s idea and that he didn’t have anything to do with it.

Joey says that Monica is an exhibitionist trying to convince him to tag along in one of her naked laps around Central Park. Monica begrudgingly agrees to go for a naked run around Central Park to keep the charade up, the rest of the gang cheering her on.

The one with the bet.

Monica and Rachel are competing with Chandler and Joey in a trivia game. As the game progresses, the wagers keep escalating until Monica proposes that the boys will get her apartment if they win.

Rachel flips out at Monica and refuses to keep playing, so the boys offer a compromise. Instead will play for the entirety of their wardrobe. Monica eagerly agrees, and they lose the game.

Monica reluctantly strips naked and gives all her clothes to the winners. She ends up without even a sock to her name. Rachel, however, begs the boys to have mercy on her, and they agree that it might be too **** of a bet. Monica refuses to beg or back down out of pride, so she stays naked as the day she was born.

Monica tries to make another wager for her clothes, but the boys refuse. Rachel is still too angry with her to lend her any of her clothes, while Phoebe is not about to break the sanctimony of a lost wager. The episode ends with the gang deciding to go for a coffee in Central Perk and dragging a bare ass naked Monica along with them.

This episode explains why Monica spends the next few episodes naked and trying to wear improvised clothing or cover up with whatever she had at hand, usually with little success. The plotline ends when Monica gives in after a particularly humiliating cocktail party she had to cater. She finally swallows what’s left of her pride and begs the boys for her clothes. They decide to give them back to her after she agrees to do half an hour of naked jumping jacks and other exercises in front of them.

Said exercise session is available uncensored and in full in all Bluray releases of the show.
