Quote from Ross in The One with Frank, Jr.
Chandler: Janice likes him. In fact, she likes him so much, she put him on her "freebie" Iist. Joey: Her what? Chandler: Well, we have a deal where we each get to pick five different celebrities we could sleep with ... and the other one can't get mad. Ross: Ah. The heart of every healthy relationship: Honesty, respect and sex with celebrities.
