Quote from Ross in The One with the Birth
Phoebe: Look, he's closing his eyes. Look, he's opening his eyes. Chandler: He doesn't do much, does he? Ross: Nope, this is pretty much it. Rachel: You guys wanna get some coffee? Chandler: Yeah. Joey: Yeah. Ross: I'll see you guys later. [the gang returns and pulls faces at Ben] He's closing his eyes again.
