Professor Sherman Klump is getting married. And the Klump family could not be more delighted for him. But Buddy Love, his Mr. Hyde alter-ego from the first film, is back and trying to make it on his own. Buddy keeps resurfacing in untimely outbursts, and threatening the portly professor's marriage plans to colleague Denise Gaines. Utilizing Denise's cutting-edge DNA research, Sherman decides to rid himself of his monstrous nemesis -and his disruptive outbursts-once and for all by extracting Buddy's DNA from his system. But Buddy bursts full-bodied into Sherman's world and lays claim to the professor's astounding invention - a revolutionary youth serum. Desperate to keep it from Buddy, Sherman hides the serum in the Klump family home, thinking it will be safe. Buddy correctly divines where Sherman has placed the serum, but to get it, he has to deal with the entire Klump family first. Written by

Sherman Klump. Well, you still eat those happy meals, you haven't changed a bit. You remember me, it's Buddy Love, we both used to chase that girl Carla at the same time.
Miss Purty and I were just friends.
Just friends, huh?

Frustrated by erratic and uncontrollable behavior at the hands of his troublesome alter ego, Professor Sherman Klump undergoes an experiment that separates his personality and allows the suave Buddy Love to become his own person. This time around they're battling each other for possession of invaluable scientific research which only further complicates matters in Sherman's personal life with colleague Jackson. Murphy, who's clearly having fun in his pull-out-all-the-stops portrayal of a horny grandmother, is as likable and energetic as he's ever been, but the script is awfully slim and throws out only a few genuinely funny ideas. A disappointment considering the impact of its predecessor. **
