The Merry Old Soul (1933)

Oswald is at the dentist. A tooth being pulled hangs on tight. Just then, the radio reports "Old King Cole has the blues" and Oswald races off in his car. He gathers up a collection of comics: Charles Chaplin, Stan Laurel, Oliver Hardy, etc. At the castle, they start singing off-kilter versions of Mother Goose rhymes, with Al Jolson in a blackface routine, and the king is quickly cheered up. Laurel & Hardy haul in a large pile of pies, and an all-out fight breaks out. The jester, who has been getting jealous of Oswald, kidnaps him during the fight and hauls him into a dungeon, submitting him to various tortures, where we discover that the real torture has been the dentist pulling the tooth all along.
