Quote from Joey in The One with the Joke
Monica: Joey, what are you doing? Joey: Just being friendly. Rachel: Joey, honey, I don't think you're supposed to go back there. Joey: No, no. It's okay. Right, Gunther? [Joey winks] Gunther: Don't wink at me. And put on your apron. Joey: Okay. I don't see you asking other paying customers to put on aprons.
