The Chimp (1932)

In lieu of back wages, the defunct circus that Stanley and Oliver have been working for pay them off with a flea circus and a trained chimpanzee named "Ethel." Unfortunately, that's also the name of their landlord's wife, and after the boys sneak the ape into their room, the jealous man draws some unfortunate conclusions when he overhears Oliver ordering Ethel to "come to bed."
