Heckle and Jeckle are postwar animated cartoon characters created by Paul Terry, originally produced at his own Terrytoons animation studio and released through 20th Century Fox. The characters are a pair of identical anthropomorphic magpies who calmly outwit their foes in the manner of Bugs Bunny, while maintaining an aggressively mischievous streak reminiscent of the early Woody Woodpecker or Screwy Squirrel. Unlike Bugs Bunny, who retaliates against a foe only after repeated provocation, their comic aggression is often unprovoked, and in a number of Heckle and Jeckle cartoons (Moose on the Loose, Free Enterprise, The Power of Thought, Hula Hula Land) their foes win in the end.
