Lippy the Lion & Hardy Har Har

Brown) and Hardy Har Har the hyena (voiced by Mel Blanc) first appeared in The Hanna-Barbera New Cartoon Series on September 3, 1962, along with Wally Gator and Touché Turtle and Dum Dum.

Mel Blanc used the same voice, personality and expressions for Hardy Har Har that he used playing the postman on the Burns and Allen radio show.

Since then, the duo have been infrequently included in the cast of Hanna-Barbera's ensemble shows (e.g., Yogi's Gang).
