Quote from Rachel in The One with Two Parts: Part 1
Monica: Oh, hi, Mr. Heckles. Mr. Heckles: You're doing it again. Monica: What? We're not doing anything. We're just sitting around talking quietly. Mr. Heckles: I can hear you through the ceiling. My cats can't sleep. Rachel: You don't even have cats. Mr. Heckles: I could have cats. Monica: Goodbye, Mr. Heckles. Rachel: We'll try to keep it down.
