#20. Paul Rudd
Mike, the guy who won Phoebe's heart was a lawyer who had given up his career to pursue his true passion: playing the piano. In that sense, he shared his musical spirit with Phoebe, who has given us wonderful songs like Smelly Cat.
In The One With The Pediatrician, we meet Mike as a result of a failed blind date that Joey and Phoebe agree to go on. The problem is that Joey completely forgets about the blind date. So right before the date, he goes to Central Perk and begins to shout out the name “Mike” to the four winds, hoping that someone would reply. Mike Hannigan happened to be at the coffee shop, and… well, you know the rest!
#19. Robin Williams and Billy Crystal
Billy Crystal and Robin Williams’s appearance wasn’t in the original script. They were, by coincidence, in the same building, or the one across the street from where the TV comedy was being filmed, and the writers asked if they wanted to make a guest appearance. This all happened on the same day of the shooting so it was just quickly thrown in.
Only these two would dare burst into Central Perk and ask the six friends to move over on the couch. If you’ve seen this episode, you probably remember the awkward moment.
#18. Charlie Sheen
Way back in season 2, Charlie Sheen played Ryan. He’s a military man who, after spending months inside a submarine, comes back to Earth and shows up at Phoebe’s apartment.

#15. Gary Oldman
Gary Oldman played Richard Crosby, a veteran alcoholic actor who shares the scene with Joey in a First World War movie. It’s funny to see such a world-renowned actor play such a strange role on the show, isn’t it?
Joey had lots of trouble when shooting his scenes with the veteran actor because he wouldn't stop spitting him in the face each time he recited his lines. When Joey confronts him, Crosby replies that spitting is a great way to emphasize words. Joey follows his advice, and the two start spitting each other during their scenes.
#14. Danny Devito
Phoebe Buffay was always portrayed as the odd one out, so it was obvious that her bachelorette party would end up being bizarre and out of the ordinary. Well, Phoebe was extremely disappointed when she discovered that Rachel and Monica hadn’t hired a stripper, so they had to look a stripper up in the yellow pages and called the first number they found...
So believe it or not, the stripper, named Officer Goodboy, was played by Danny DeVito. If you’ve seen the episode, I’m sure you vividly remember Danny DeVito’s erotic costume and sexy dance!

Yes, when Brad Pitt appeared on Friends, he and Jennifer Anniston were still together! What makes the episode even funnier is that Brad plays the role of Will Colbert, Ross’s former best friend from high school, who hates Rachel with all his heart.
The famous actor wasn’t the only one of Aniston’s couples who made a small appearance in the production. Another of his boyfriends, Tate Donovan, also appeared in several episodes, playing the role of the attractive Joshua, a client she intended to conquer at all costs.
