Justice League, Season Two

Joker:
Here's how we do this little tango: I've tucked away a great, big time bomb somewhere on the Vegas strip. Only the Justice League can defuse it, 'cause if anyone else tries, (shows audience a switch) I press this, and kablooie! No waiting! Now, I know you want to see the big bomb hunt from the best point of view, so I've set up hundreds of cameras all over town! The League won't be able to burp without us looking in! And since every good suspense show has to have a ticking clock, here's mine! (a display appears on screen, counting down from 23 minutes - the average length of an episode without commercials) Oh, what were you expecting from me? A round number?
