The Whoopee Party(1932)

A house party. While Minnie plays piano and the guests dance, Mickey, Goofy, and Horace prepare a snack, which is brought out to much fanfare and immediately devoured. A band forms and plays Scott Joplin's The Entertainer; Mickey dances with Patricia Pig and various inanimate objects also dance, while all cry "Whoopee!" from time to time. The police come to break up the party.
