Quote from Phoebe in The One with Rachel's Book
Phoebe: Look, Ross. I really need that $80 every week. Ross: Look, I'm sure you'll find another massage client, Phoebe. Phoebe: Yeah, I'm sure I will, too. But until then I'm gonna massage you every week for the price of $100. Ross: You just said 80. Phoebe: Do you want me to mess up your puzzle? Ross: A hundred it is.
