Quote from Joey in The One with Rachel's Other Sister
Joey: No, no, no. I need a good lie to explain why I wasn't at a work thing today. Phoebe: Ooh. Honey, you stink at lying. Joey: I do not. Phoebe: Oh, really? Let me ask you something. Yesterday at the coffeehouse I went to the bathroom and when I came back, my muffin was gone. Who took it? Joey: Somebody opened the door to the coffeehouse and a raccoon came running in and went straight for your muffin. I said: "Hey, don't eat that. That's Phoebe's." And he said- He said, "Joey, you stink at lying."
