Fresh Hare (1942)
Mountie Elmer is on the trail of Bugs who's wanted dead or alive, "preferably dead". Elmer gets handcuffed to a bomb. Bugs looks through all Elmer's keys but can't seem to find the right one... Bugs foils Elmer with tricks like the Elmer-shaped snowman. Finally Bugs lets himself be arrested. Elmer takes Bugs back to the log stockade and puts Bugs up before a Mountie firing squad. But Bugs starts singing "Dixie". The stockade becomes a field of cotton, and all the Mounties, including Elmer, turn into singing Negro minstrels!
