You guys have mentioned most of the good ones! Ross is definetly the funniest character.
Not so good with the names of episodes, but the one where Ross has rage issues and his boss eats his 'moist-maker'. Ross: "My sandwich! MY SANDWICH!" As the pigeons in Central Park fly away.
The one where Phoebe breaks up with Mike's girlfriend for him.
Phoebe: Suzie? Can I call you Suzie?
Precious: But my name is Precious!
Phoebe: Yeah...I can't call you that. Lol.
The one with Ross's Tan is simply the best! I almost died laughing.
