Jealous Jeannie has promised not to interfere with Tony's social life, but she breaks that promise when she finds out that Tony (Larry Hagman) is planning to meet his old girlfriend Joan (Joan Patrick). In a snit, Jeannie transforms Joan into a chimpanzee, hoping that this will teach her Master a lesson. What Jeannie doesn't know is that Joan is married to a vicious mobster named Two Gun Richards (Ted De Corsia), a fact that will determine the riotous outcome of the story! ~ Hal Erickson, Rovi
