 For his birthday Izzie Cohen wants a motorcycle, but his father gives him a camera instead. Izzie takes a photograph of his father in an apparently compromising (although actually harmless) position and uses it to blackmail him into buying the motorcycle. When the motorcycle arrives, Izzie s father gets into it and starts it accidentally. He can neither turn it off nor control it, and it runs wildly around the house before crashing through the house of his Irish neighbor, Murphy. The motorcycle exits Murphy s house, dragging Murphy along in a bathtub. Murphy and Cohen continue on a wild ride, pursued by Izzie and a traffic cop. Finally the motorcycle hits a tree and stops. The cop arrests Cohen and Murphy for reckless driving.
