BTAS - Make'em Laugh

In this animated episode, the Joker tries to become the funniest comic in Gotham by stealing the comedy crown and rigging the competition. He uses the Mad Hatter's mind control microchip to turn the comedic judges into bizarre superheroes. Batman figures out that the Joker is behind all of this after watching a video of last year's competition and editing the video on the Batcomputer to alter the appearance of one of the disgraced participants to reveal that the participant was really the Joker.
