الموسم 3، الحلقة 1: Roger and Tony are disappointed when they find that Sam, a chimpanzee will make the first flight to the moon. Learning this, Jeannie changes Sam into a man working around the base. When Sam jumps into Tony's arms and cries that he won't go back in the cage, Tony and Roger realize Sam is the missing chimp. To keep his human form, Sam runs away. Tony and Roger find him in a tree, determined to stay there until the capsule goes up. Even if they capture Sam, they can't change him back into a chimp. Tony tries to reach Jeannie by telepathy at the beauty parlor. When she finally phones Tony, he orders her to turn Sam back into a chimp. As the beautician distracts Jeannie, her blink goes wrong and Tony turns into a chimp. Dr. Bellows is sure that Tony is Sam. When Tony writes a message, Bellows thinks he has found the Missing Link. Roger tells Jeannie what has happened to Tony. As Sam is making a play for her, Jeannie blinks. Tony returns to human form and Sari reverts to being a chimp. In General Whitfield's presence, Dr. Bellows dictates the "Gettysburg Address" to Sam. When the monkey fills the page with meaningless scrawls, the General upbraids Dr. Bellows. Later, Tony, Roger and Dr. Bellows follow Sam's progress in space. Jeannie blinks again and they are stunned to hear Sam's human voice complaining of all the trouble they are making for him.
