To you whats the FUNNIEST EVER moment on friends ever ever ever?

There are so many! I seriously can't choose, I amor Friends! :D

Ross trying to get his tight leather pants off in a bathroom, with the help of powder and Joey on his cell phone....

That beijoca, smack on his head when he was trying to pull up his pants is PRICELESS!!! hahaha :D

I think when Pheobe is trying to teach Joey French and also when ross gets kneed while Rachel is giving birth

I amor the scene in TOW Everybody Find's Out, when Phoebe, Ross, and Rachel are looking at Ugly Naked Guy's apartment. Phoebe seeing Monica and Chandler having sex across the rua and screaming "My eyes!" is hilarious! And of course that is followed por Ross's scream when they start jumping around :D

The One At The Beach, Joey is so desperate to play Strip Poker and then they all make him take off his clothes! Haha xD!

Or, when Monica is convinced that the maid is stealing her clothes, and tries to look at her crotch, lmao...

I like all of them! xD And the only one I could think of right now, it's:

Chandler: What are we gonna do? What are we gonna DO!?
Joey: Uh, uh, we'll flip for it, ducks or clowns.
Candler: Oh, we're gonna flip for the baby?
Joey: You got a better idea?
Chandler: All right, call it in the air.
Joey: Heads.
Chandler: Heads it is.
Joey: Yes! Whoo!
Chandler: ... We have to assign heads to something!
Joey: Right, okay, okay, uh, ducks is heads, because ducks.. have heads.
Chandler: What kind of scary-ass clowns came to your birthday!?.

I'll editar my answer when I remember other moments. :)

THERE IS NO WAY I COULD PICK ONE. ITS JUST NOT POSSIBLE....
