Say what you want, but Calendar Man was one of the weirder and wackier Batman villains from his earlier days that somehow still survived into his new canon as well. For the few of you out there who wish to know more about this mathematical moron, we have the perfect video for you.

Worth watching just for The Brave and the Bold clip. God, we miss that show.
