Mickey Steps Out (1931)

Animation. Mickey heads over to see Minnie, but Pluto won't leave him alone. He gets there and watches through the window, standing on Pluto, while Minnie plays piano. Pluto runs off to chase a cat and leaves Mickey stuck in the window. Minnie has him in, and he dances to her playing. Pluto chases the cat into the house and causes havoc. The chase leads into the piano, where Pluto picks up the player-piano roll as an extended tail, and the destruction continues.

At 05:29, Mickey Mouse balances a broom on his nose with a fishbowl on top complete with two fish, while spinning a plate on one finger and spinning another plate on an umbrella in his other hand, all for 4 seconds. A few seconds later he improves on this by adding several more objects to the balances, until Pluto trips him, with disastrous consequences.
