Sinkin' in the Bathtub was the very first Warner Bros. theatrical cartoon short as well as the very first of the Looney Tunes series.
The film opens with Bosko taking a bath while singing "Singin' in the Bathtub". A series of gags allow him to play the shower spray like a harp, pull up his pants by tugging his hair, and give the limelight to the bathtub itself which stands on its hind feet to perform a dance.
