Rachel: Listen, you know what, I'm not feeling really well and I don't think I'm gonna get to go to the play.
Ross: Really? What's wrong?
Rachel: I don't know. I think it's kind of serious. You know, I was watching this thing on TV this morning about Newcastle disease, and I think I might have it.
Charlie: Newcastle disease is a secretion-borne virus that only affects chickens and other poultry.
Rachel: Okay, who's this?
Ross: I'm sorry. Rachel, this is Charlie Wheeler. She's a colleague.
Rachel: Oh, hi. Well, I would shake your hand but I'm sure you don't want to get my chicken disease.
