Eddie Murphy returns as Professor Sherman Klump (not to mention Ernie Klump, Granny Klump, and Mama and Papa Klump) in this sequel to the popular 1996 comedy. Having decided to get married, the portly professor asks for the hand of fellow scientist Denise Gaines (Janet Jackson) and is overjoyed when she accepts. But when Klump's fast-talking alter-ego Buddy Love comes back on the scene, the ensuing havoc threatens to ruin all the professor's plans.
