Eddie Murphy returns as Professor Sherman Klump (not to mention Ernie Klump, Granny Klump, & Mama & 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) & 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.
