Quote from Phoebe in The One Where Monica and Richard Are Just Friends
Joey: Look at you. Since when do you rollerblade? Phoebe: Oh, since tomorrow. I met this really cute guy in the park. And he jogs and blades and swims and so we made a deal. He's gonna teach me how to do jock stuff. Ross: And what are you gonna do for him? Phoebe: I'm gonna let him.
