Porky Pig is listening to the radio. Somebody just won $10,000 on a game show. Porky changes channels and hears a radio voice telling him that he may be the winner of the grand prize. The grand prize is delivered to Porky's door. To Porky's surprise, the prize is Daffy Duck. Daffy wasted no time in doing his usual antics, but Porky just can't put up with him. So Porky threw Daffy out. Daffy then tries to scare Porky each time Porky mistreats him. He uses fake vampire teeth and messed up his hair to do the trick. Eventually Porky finds out, and pays him back by scaring Daffy. He puts on a Halloween costume and scares Daffy out of the house. The cartoon ends with Porky scaring himself.
It has recently been discovered that a print of this cartoon with the original opening titles uses the same head shots of Porky and Daffy from "Riff Raffy Daffy". Despite the existence of the original print, the restored version as seen on Looney Tunes Super Stars' Daffy Duck: Frustrated Fowl is the Blue Ribbon version (it is not known if WB was aware of the original print's existence or not).
