Quote from Ross in The One with the Prom Video
Ross: Okay, here you go. You can pay me back whenever you like. Monica: You have dinosaur checks? Ross: Yeah, yeah. I mean, you get your money and you learn a little something. What's wrong with that? Monica: Nothing. Nothing. Hey, you're a cheap-a-saurus. I'm kidding, I'm kidding. Thank you, I'm very grateful.
