Storyline

As Betty Boop ices a cake for Grampy, her obnoxious cousin Irving stops by the house to pay a most unwelcome visit. She endures several of his unfunny practical jokes, including a fake hand that squirts water in her face, a phony box of candy with a jack-in-the-box devil inside, and pipe smoke that turns into a snake. Once she has had enough, she enlists Grampy's help in ridding her of this pest. Grampy puts on his thinking cap, which allows him to come up with a series of gags that cause Irving's practical jokes to backfire on him. For instance, the hotfoot intended for Grampy becomes a hot seat for Irving, and so on. Soon, Irving is desperate to get out as everything in Grampy's contraption-filled room proves to be booby trapped.
