Quote from Chandler in The One with the Baby on the Bus
Chandler: Please tell me you know which one is our baby. Joey: Well, that one has ducks on his T-shirt and this one has clowns. And Ben was definitely wearing ducks. Chandler: Okay. Joey: Or clowns. Oh, wait, wait. That one's definitely Ben! Remember he had that cute little mole by his mouth! Chandler: Hey, Ben! Remember us? Okay, the mole came off. What are we gonna do? What are gonna do? Joey: We'll flip for it. Ducks or clowns. Chandler: 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. We have to assign heads to something! Joey: Right! Okay, okay. Ducks is heads because ducks have heads. Chandler: What kind of scary-ass clowns came to your birthday?
