Heckle and Jeckle

Heckle and Jeckle are 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 Danny Webb (1946-47), Sid Raymond (1947), Dayton Allen, Ned Sparks (1950), Roy Halee (1950-60), and Frank Welker (1979).
