The Dirdy Birdy

The Dirdy Birdy is an animated short created by John R. Dilworth, creator of Courage the Cowardly Dog. It features a dimwitted bird name Purdy who falls in love with a cat named Fergurina. The short consists of Purdy trying to win Fergurina's affections (by showing his backside of all things) and getting rejected (and pummled) in the process.

It can be seen here.
