Hare-um Scare-um is a 1939 Warner Bros. Merrie Melodies cartoon directed by Ben Hardaway and Cal Dalton. The short was released on August 12, 1939, and is the third short to feature the rabbit that would evolve into Bugs Bunny. The title is a homonym with an old nonsense expression — "harum-scarum", meaning reckless or irresponsible. This was the first use of a hare-based pun title in the Warner Bros. cartoons; it would be a device used to name many Bugs Bunny cartoons in the years to come. Wikipedia
