After an ill advised comment to an athlete in his chemistry class, Professor Kelp (Jerry Lewis) decides he needs to become more manly. He finds himself falling for a beauty in his class and overuses this fountain of cool youthfulness formula he creates. If it wears off it's trouble. But now he has Stella Purdy's (Stella Stevens) attention and cannot bear to lose it. After her frustration increases over this egotistical rebel Buddy Love (Jerry Lewis), she tells Kelp her feelings. SPOILER WARNING. And just in time because Kelp's about to blow it big time by a mistake with the potion. Playing his first big venue, the gig is up for buddy Love. With the truth now evident, only Stella can find a way to take the Jekyll and Hyde relationship and create a better, complete relationship. She becomes the hero, creating a relationship with a now confident, dutiful man which the professor could not do with his previous schizophrenia. But what will become of the macho-man formula?
What is the name of the Professor's alter ego?
Buddy Love
