Ain't We Got Fun is a 1937 Merrie Melodies cartoon directed by Tex Avery. The cartoon was released on May 1, 1937. The title is based on the popular song of the same name. This is one of a rare handful of Warner Bros. cartoons (which also include "The Night Watchman", "We, the Animals - Squeak!", "Scaredy Cat", "Claws for Alarm" and "Kiss Me Cat") in which the cats are depicted as the heroes and the mice as the villains rather than vice versa.
