Long before Bill Murray and company wiped out all the ghosts in New York City, Mickey, Donald, and Goofy were doing the job (but not in NYC, and without the proton packs and other gadgets, of course). In this classic 1937 short, the trio are ghost hunters who go into a haunted house, where they end up having some wacky adventures (Goofy gets stuck in a dresser, etc.). In my opinion, this is definitely one of the best of all the Disney shorts (and there are many to choose from). And the ending of this one is just PERFECT.
