The Monkey's Uncle is a 1965 American comedy film starring Tommy Kirk as genius college student Merlin Jones and Annette Funicello as his girlfriend, Jennifer. The title plays on the idiom "monkey's uncle" and refers to a chimpanzee named Stanley, Merlin's legal "nephew" who otherwise has little relevance to the plot. Jones invents a man-powered airplane and a sleep-learning system. The film is a sequel to 1964's The Misadventures of Merlin Jones.
