In "The One With a Chick and a Duck." (season 3), Joey and Chandler adopt a chick from an animal sanctuary, misunderstanding a news report about people who buy chicks and then find they cannot properly care for them. Encouraged by Phoebe to return the chick, but discovering that the animals would be euthanized, Chandler returns home with the chick and a duck. Chandler names the chick Yasmine and refers to the duck as Dick. Chandler and Joey treat the chick and the duck as their own children.
CHANDLER: (to the duck) You stay out here and think about what you did!
