Phoebe: Oh, you have got to sing.
Monica: No, I told you I can't. But you would have so much fun. And you have a really nice voice.
Monica: When have you heard me sing?
Phoebe: All the time, when you're cooking.
Monica: What?
Phoebe: Yeah, you're always singing: "Yummy, yummy, yummy, I've got love in my tummy"
Monica: Yeah, I do rock that one.
