Quote from Chandler in The One with the Embyros
Rachel: [rooster crows] What the hell is that?! What the hell is that? Is that you? [groans] Monica: Boy, you are really not a morning person. Rachel: Just back off! [pounding on Chandler and Joey's apartment door] Get up! Get up! Get up! What is that noise? Chandler: You. Joey: It's the chick. She's going through some changes. Monica: What kind of changes? Chandler: The vet seems to think she's becoming a rooster. [rooster crows] We're getting a second opinion.
