Quote from Joey in The Last One (Part One)
Phoebe: What's that? Joey: It's my house-warming present for Monica and Chandler. Phoebe: It's a baby chick and duck. Joey: Uh-huh. And I named them Chick Jr. and Duck Jr. Phoebe: I did not see that coming. Joey: Yeah, I figure they'll love it at the new house, you know? It has that big backyard. And then, when they get old, they can go to that special farm that Chandler took the other chick and duck to. Phoebe: Yes. Joey: Yeah. It's a shame people can't visit there. Phoebe: That is the rule, though.
