You know the old adage "Keep your friends close and your enemies closer"? In the cartoon and comic jungle this has been a long standing mantra. "Friendly" foes like Looney Tunes Sam Sheepdog and Ralph Wolf would punch into work before punching each other. But they weren't necessarily causing or fighting crime. For that you have to go the big city. In Gotham, The Batman and The Joker never needed a punch-clock in order to "go-to-town" on each other. But an alliance between the two crazy talk? How did these unlikely partners thwart The Red Skull, The Penguin and Alex Luthor? And honestly how long would the Bat hold off until trying to take The Riddler, Catwoman and Poison Ivy into custody? Because you know with the Joker these three are a package deal.
