Hare-um Scare-um is a 1939 Merrie Melodies cartoon directed by Ben Hardaway and Cal Dalton, and first released on August 12, 1939 by Warner Bros. It marks the third appearance of Happy Rabbit and the first time he, thanks to a redesign by Charlie Thorson, appears as a grey rabbit instead of a white one resembling Bugs Bunny. The title is a homonym with an old nonsense expression that has nothing to do with rabbits as such. The voices are done by Mel Blanc, although he is not mentioned as his exclusive contract was yet to be created.
