In this animated feature, wealthy J.P. Cubish has promised his fortune to anyone who can make him laugh. After Cubish dies, Daffy Duck, who won the job of personal court jester, lands the inheritance. The rub is that Cubish has demanded the person who receives his money use the funds for good. Daffy mocks the notion until Cubish's ghost starts haunting him. Determined to be rid of the spirit, Daffy recruits his friends -- Porky Pig, Bugs Bunny and others -- to start a ghost-busting service.
