The Laurel & Hardy Moving Co. have a challenging job on their hands (and backs): hauling a player piano up a monumental flight of stairs to Prof. von Schwarzenhoffen’s house. Their task is complicated by a sassy nursemaid and, unbeknownst to them, the impatient Prof. von Schwarzenhoffen himself. But the biggest problem is the force of gravity, which repeatedly pulls the piano back down to the bottom of the stairs.
