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 yellow-billed magpies who usually cause problems to others and for themselves with their bizarre antics. Heckle speaks in a tough New York style manner, while Jeckle has a more polite British accent. They were voiced at different times by Dayton Allen (1946–66), Sid Raymond (1947), Roy Halee, and Frank Welker (1979).
