Quote from Joey in The One Where No One's Ready
Joey: Where's my underwear? Ross: Come on, you took his underwear? Chandler: He took my essence! Ross: Okay, hold on. Joey, why can't you just wear the underwear you're wearing now? Joey: Because I'm not wearing any underwear now. Ross: Okay. Then why do you have to wear underwear tonight? Joey: It's a rented tux, okay? I' m not gonna go commando in another man's fatigues.
