Quote from Chandler in The One on the Last Night
Chandler: I invented the game of Cups as a way to give Joey money. Ross: And now you want that money back? Chandler: Exactly. Ross: Chandler, what kind of idiot do you take me for? Chandler: It's not a real game. I made it up. Ross: I'm sorry you lost your money. But I won it fair and square. Chandler: At a fake game! Ross: Now, if you wanna try to make some of it back, I'd be glad to play you for it. But I should warn you. I am very good at Cups. Chandler: Okay, now, I assume the saucer card came up when you played last? Ross: No. Chandler: Hmm, let's see if it comes up this time.
