Carl: What's with this guy?
Arthur: What's with you?
Ross: Nothing. Nothing's with him. Enjoy your coffee.
Chandler: What just happened?
Arthur: I just took your hat. See, I can be funny too. My joke is that I took your hat.
Chandler: That is funny. Can I have it back?
Arthur: No.
Chandler: No?
Arthur: No.
Ross: Okay. You know what? I think you're very funny. Kudos on that hat joke. [laughs] But come on, guys, just give him back the hat.
Carl: Why should we?
Ross: Because it's a special hat. See, he bought it because he was feeling really down one day. So he got the hat to cheer himself up, you know? Chandler-
Chandler: Stop talking. Stop talking now.
