Two baby squirrels ask grandpa to explain what "men" are when he comes in singing "peace on earth, goodwill to men". Grandpa tells the story of man's last war. This classic animation short was an Academy Award Best Short Subject, Cartoons nominee.

The film opens with Bosko taking a bath while whistling "Singin' in the Bathtub". A series of gags allows 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.

A dark and stormy night in a drugstore. The druggist mixes a potion and falls asleep. The skull-and-crossbones on the bottle comes to life and drips the potion on the druggist…

Bosko runs a movie theater that shows a wacky newsreel with Jack Dumpsey, a slapstick short from Haurel and Lardy, and a turn-of-the-century melodrama starring Honey.

Bosko is a doughboy in the Great War.
