The Monkey's Uncle is a 1965 American comedy film starring Tommy Kirk as genius college student Merlin Jones and Annette Funicello (former Mouseketeer from The Mickey Mouse Club) as his girlfriend, Jennifer. The title plays on the idiom "monkey's uncle" and refers to a chimpanzee named Stanley, Merlin's legal "nephew" (because of a legal arrangement resulting from an experiment to raise Stanley as a human) 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.
