Plot

Old secrets come to light when Ross and Chandler attend a college reunion. Monica and Rachel throw Phoebe a bachelorette party. Joey appears as a celebrity partner on a game show.

Phoebe's bachelorette party has no strippers, but Phoebe had wanted one - so Rachel and Monica hurriedly hire a stripper, but he turns out to be at least 50 years old, and under 5 feet tall. Joey appears as a celebrity partner on "Pyramid", but his narrow frame of reference produces less-than-desirable clues and answers. Chandler and Ross go to a college reunion, and recall what they did as freshmen in 1987, inadvertently revealing that they had both broken their longtime pact about dating. Chandler tells Ross that he kissed Rachel at a party, and Ross gets upset because that was the night he thinks he kissed Rachel for the first time - but Monica remembers the night differently.

Rachel and Monica throw Phoebe a clean and elegant hens party, unbeknownst to them that Phoebe really wanted a typical, wild party complete with a male exotic dance show. Upon Phoebe's request, Rachel and Monica quickly go through the yellow pages and find one telephone number for a male exotic dancer. The dancer (Danny DeVito) arrives dressed in a police officer costume, however to the girls' dismay, he turns out to be an old, dimwitted and ugly dwarf who started panting by just climbing a few stairs.

Realizing that the ladies are cringing at his performance, the dancer gets mad and depressed. Phoebe refuses to allow Rachel to pay him his fee ($300.. he says he took a bus from Hoboken and climbed a billion stairs to reach there), causing the stripper to cry (Phoebe calls him an old man in a Halloween costume) and decide to leave the profession once and for all. Feeling sorry for him, the ladies feel sorry for him and comfort him, eventually convincing him to teach stripping to younger men and pass on his wisdom to them. They also allow him to put on one more striptease routine for them which they all end up enjoying anyway.

Meanwhile, Joey appears on the celebrity game show, "Pyramid", where he loses almost every round (In the first round, he had to give the clues, but messed each one), though his partner's clues are apparent and simple. His partner was Gene Lester. Gene has one more chance to go to the winner's circle and have a chance of winning $10,000. He has a kid going to college and he needs surgery on his knee. He needs the money. Joey pairs up with Gene's opponent and Joey doesn't get even a single clue about US congress. The rival gets zero points and Gene goes to the winner's circle with Joey. Gene had almost given up but Joey starts guessing the clues right, but doesn't get the last one "SuperModels" (he guesses: Girls that Chandler can never get). Gene goes home without any money.

Chandler and Ross go to a college reunion, recalling the various misadventures that they experienced in 1987. They both run into Missy Goldberg (Ellen Pompeo) and remember that they both had a crush on her in 1987 and made a pact never to ask her out, lest it comes in between their friendship. Now, Ross asks Chandler for permission to break the pact and ask her out. When Ross speaks to Missy, he finds that Chandler used to make out with her, a lot. Ross confronts Chandler and Chandler says even he broke some pacts. Ross kissed Adrienne (who was also under a pact) at the college Christmas party, where he invited Rachel and Monica. That night Chandler was angry, and wanted to hurt Ross. Chandler tells Ross that he kissed Rachel at a party in college, which upsets Ross because that was the night he kissed Rachel for the first time as well. Later at Monica and Chandler's apartment, Ross and Chandler tell Monica that Rachel had kissed the both of them at the college party. When Ross said that Rachel was on his bed, Chandler reveals he put Rachel on his bed. This causes Ross to wonder who was on his bed, before Monica realizes she was and Ross is disgusted to realize that it wasn't Rachel who he had kissed, it was Monica, his own sister. In horror, Monica realizes that Ross, her own brother was her first kiss ever. After hearing these details, Chandler is stunned and questions what kind of family he married into.
