The Joker: [over the PA] Tonight you're all gonna be part of a
social experiment. Through the magic of diesel fuel and ammonium
nitrate, I'm ready right now to blow you all sky high. Anyone
attempts to get off their boat, you all die. Each of you has a
remote... to blow up the other boat. At midnight, I blow you all
up. If, however, one of you presses the button, I'll let that
boat live. So, who's it going to be: Harvey Dent's most wanted
scumbag collection, or the sweet and innocent civilians? You
choose... oh, and you might want to decide quickly, because the
people on the other boat might not be so noble.
