A Walter Lantz's Oswald cartoon where he's looking for gold but soon becomes a gag fest with a singing waiter who ends his verses with someone "who cannot leave his mother", a piano player who keeps chugging beer, and Oswald and his peg-leg buddy (probably Peg-Leg Pete who eventually became Mickey's nemesis) saying in unison "Pop Goes the Weasel" with the rabbit getting the better of this buddy after he keeps hitting him.
Sound
"Pop Goes the Weasel" as violent punchline—surreal musical comedy.
Director
William Nolan
Trivia, insights & behind the scenes
This was Oswald before Disney lost him to Universal—Mickey's forgotten older brother in full pre-Code weirdness.
The 'cannot leave his mother' gag reflects 1930s vaudeville humor about mama's boys that modern audiences find inexplicable.
