Riddler: "It's simple Batman. Play the little poker game with us that I've crafted. If you win, the Robin is freed. Lose a hand and we get to change you in any fashion we like! Deal?"
Batman: "The game is rigged."
Riddler: "Absolutely! But you're still in brave Bats?"
Batman: "Only because there is no other choice."
Riddler: "La dee dah! Make some room everybody! Batman's come to play!"
