Great sequence (from memory):
(Chandler has just had a confrontation with Janice and is angrily hurling darts at the wall when Joey comes in)
Joey: You know how we save all those chopsticks whenever we have Chinese food, for no reason?
Chandler: Mm-hm?
Joey (triumphantly): Well now we have a reason!
(Joey gets out a huge pile of chopsticks)
Joey: We're going to poke a naked guy!
Chandler: Mm-hm.
Joey: Say man, what's happened?
Chandler: I talked to Janice. She's still in love with him. And me.
Joey: So what are you going to do?
Chandler (really swinging back and hurling darts into the dartboard): I don't know. What would you do?
Joey (nervously watching him throw the darts): Me? I would - and this is just me, you understand, not you, it's just -
Chandler: Yeah?
Joey: I'd back out.
Chandler: WHAT?!
(He spins around as he's about to hurl another dart - Joey throws himself to the floor).
