Fantasia - The Sorcerer's Apprentice by Paul Dukas. Based on Goethe's 1797 poem "Der Zauberlehrling". Mickey Mouse, the young apprentice of the sorcerer Yen Sid, attempts some of his master's magic tricks but doesn't know how to control them.
So sad, but this is why I love goofy and why I think Disney did such a great job developing him as a character over the years. And another reason why I hate mickey mouse club house! They dumb down all their characters. Especially pete and goofy.
