The Nutty Professor synopsis
Brilliant and obese scientist Sherman Klump (Eddie Murphy) invents a miraculous weight-loss solution. After a date with chemistry student Carla Purty (Jada Pinkett) goes badly, a depressed Klump tries the solution on himself. Though he instantly loses 250 pounds, the side effects include a second personality: an obnoxiously self-assertive braggart who calls himself Buddy Love. Buddy proves to be more popular than Sherman, but his arrogance and bad behavior quickly spiral out of control.
