A Knight for a Day

A Knight for a Day is a Goofy short released 8 March 1946. All of the characters including the princess are Goofy lookalikes.

Summary
At a jousting field in medieval Canterbury, a jousting competition is held between Sir Loinsteak and Sir Cumference, the black knight, with a sportscaster-like announcer calling the action of the battle. The prize for this contest is the right to marry Princess Esmeralda.

Due to an accident, Sir Loinsteak is knocked out, leaving his sappy yet clever squire, Cedric, to take his place in the tournament. While Sir Cumference early dominates the inexperienced simpleton, Cedric's clever and unorthodox improvisations tip the scales in the youth's favor. Finally after an assault with his lance, sword and mace, Sir Cumference collapses from exhaustion and Cedric wins by default. Princess Esmeralda leaps to her new fiancé with glee, Cedric soaks in the crowd adoration, while a serf nonchalantly pushes Sir Cumference from the field in a scoop shovel.
