Heckle and Jeckle are postwar animated cartoon characters created by Paul Terry, originally produced at his own Terrytoons animation studio. 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.
Although identical in appearance, they are differentiated by their voices. Jeckle speaks with a slightly falsetto English accent, and his dialogue is somewhat more refined. Heckle is more rough around the edges, and speaks with a more informal, slangy vernacular and gruff New York City dialect. However, the two magpies are far more alike in temperament than they are different. The characters seldom referred to each other by name, leading to some confusion as to which one was which. Heckle usually refers to Jeckle familiarly, as "chum" or "pal", while Jeckle often calls Heckle "old chap", "old thing", "old boy" or "old featherhead", indicating a close friendship between them.
Heckle and Jeckle first appeared in "the talking Magpies" in January 1946; and made their final appearance in "Birds of Paradise" in 1981.
As you can imagine you are looking for a Birdhouse.
