Felix the Ghost Breaker (1923)
Felix is trying to get some sleep in a graveyard, but keeps getting bothered by a ghost. He follows the ghost to the house of an old farmer, and the ghost proceeds to terrorize the old man, and when the farmer calls for help from the police, the ghost terrorizes them, too. Felix, however, suspects something fishy is going on, and with the help of the farmer's donkey, gets to the bottom of things.
