- The Joker: There are only two ways to get out of there. One: I let you out. And two: you jump fifty feet straight up!
- Batman: You still intend to free us if we can stay afloat for an hour?
- The Joker: Oh, dear me! Surely you don't think I'd joke about such a serious matter as that, do you? Time to start filling the tank!

- Robin: But you can't float in gas!
- The Joker: No, but you can drown in it!
