The Santa is Detective Jimmy "Popeye" Doyle (Gene Hackman) and the vendor is his partner, Detective Salvatore Russo (Roy Scheider), whom Doyle nicknames "Cloudy." The two narcotics cops are staking out the bar in hope of finding a pusher named Willie (Alan Weeks).

Generate a question that has the following answer: Secrets of life for the following movie plot: Professor Julius Kelp is a nerdy, scruffy, buck-toothed, accident-prone, socially awkward university professor whose experiments in the classroom laboratory are unsuccessful and highly destructive. When a football-playing bully embarrasses and attacks him, Kelp decides to "beef up" by joining a local gym. Kelp's lack of physical strength prompts him to invent a serum that turns him into the handsome, suave, charming, and cheeky girl-chasing hipster, Buddy Love. This new personality gives him the self-confidence to pursue one of his students, Stella Purdy. Although she resents Love, she finds herself strangely attracted to him. Buddy wows the crowd with his jazzy, breezy musical delivery and poised demeanor at the Purple Pit, a nightclub where the students hang out. He also mocks a bartender and waitress and punches a student. The formula wears off at inopportune times, often to Kelp's humiliation.

As Buddy performs at the annual student dance the formula starts to wear off. His real identity now revealed, Kelp gives an impassioned speech, admitting his mistakes and seeking forgiveness. Kelp says that the one thing he learned from being someone else is that if you don't like yourself, you can't expect others to like you. Purdy meets Kelp backstage, and confesses that she prefers Kelp over Buddy Love. Eventually, Kelp's formerly timid father chooses to market the formula (a copy of which Kelp had sent to his parents' home for safekeeping), endorsed by the deadpan president of the university who proclaims, "It's a gasser!" Kelp's father makes a pitch to the chemistry class, and the students all rush forward to buy the new tonic. In the confusion Kelp and Purdy slip out of the class. Armed with a marriage license and two bottles of the formula, they elope. During the short closing credits, each of the characters come out and bow down to the...
