Portrait of the Artist as a Young Bunny (1980)

Bugs Bunny gushes with excitement over the end of school, but while stopping to wonder why he's excited about this at his age, he runs into a tree and has a flashback to his youth, when he was just as excited about the end of school. But his nemesis, a young Elmer Fudd, is also out, and he's out to get the budding wascally wabbit.
