[There are two boats in Gotham Harbor, a yeoman approaches the captain]
YEOMAN: Sir, the whole boat is rigged to explode! And I found this! [displays a detonator]
[meanwhile, all the passangers are in the seating area, the intercom turns on]
JOKER: Greetings from the Joker. "Why so serious?" Anyway, we have a boat of civilians and a boat of prison inmates. I will blow up both boats at midnight.
MAN#1: Oh, my God!
JOKER: However, each boat has a detonator that will blow up the opposite boat. If one boat decides to blow up the other boat prior to midnight, I will not blow up the boat that blows up the other boat. It's quite the moral quandary, is it not?
MAN#2: Then let's vote on neither boat blowing up.
GIRL: No, he said we decide.
MAN#3: Then I decide that neither boat blows up!
CAPTAIN: Wait, wait...so, we vote?
WOMAN: No, we... we just press a button, I think.
MAN#4: I don't understand. What does this prove, exactly?
MAN#5: Uh, Mister Joker, sir? We came to a consensus: we vote that neither boat should blow up.
JOKER: That's not a choice!
MAN#5: Uh..uh, you better explain it again then, I guess.
JOKER: (sighs) I will blow up both the boats-
MAN#1: Oh my God!
JOKER: -unless, UNLESS, one boat blows up the other boat first.
MAN#5: Uh, w-what are the other options?
JOKER: There are no other options.
OLD LADY: Ask him when both boats blow up.
JOKER: MIDNIGHT! MIDNIGHT! MIDNIGHT!
CAPTAIN: Alright folks, that gives us a good 15 minutes. Everyone, into the lifeboats!
JOKER: No, no lifeboats! I said that you couldn't use them.
MAN#6: You never said that!
JOKER: I did, way back in the beginning.
MAN#5: You better go over the rules again.
[the Joker is clearly exhasperated]
JOKER: Oh, for H- it's a catch 22! Look, there are two boats. At midnight-
[Batman cuts him off by hitting him with a board.]
