Mickey, Donald, and Goofy are assigned to clean a tall clock tower. Mickey is outside cleaning the face with a mop by riding on the second hand. Goofy is inside the building cleaning gear teeth with a large toothbrush. Donald (singing "Hickory Dickory Dock") starts to mop the mainspring, ignoring several warning signs.
