Her Honor, the Mare (1943)

Popeye's nephews happen by just as the glue factory is rejecting a sorry looking horse and decide to take it home. They want to treat it as a house pet, despite the obvious problems; Popeye says no. They try to hide it, including painting a Hitler face on its rear and calling it a painter, but keep making mistakes like feeding it horseradish (great reaction shots). Finally, they hide the horse in the closet; Popeye comes out and says that they'll have to keep it now. We see why when she's sitting at the table with her four new foals.

Her Honor, the Mare has a runtime of 7 minutes.
