Fight that ghost (1946)

Pigmeat and Shorty, who own "Pigmeat and Shorty's Bootery", are told by their landlord to either pay up or get out. They get caught trying to short-count him, and he threatens to have them arrested. After a series of disasters--they ruin a customer's suit, their store blows up--they get a telegram notifying them that a man they once did a kindness for has left them quite a bit of money and a house, but in order to get the inheritance, they have to spend a night in the bedroom of the man's house. When they arrive there, they notice two things--the place is kind of creepy and a series of spooky incidents leaves them to believe the house is haunted.
