Nutty Professor II: The Klumps

Sherman Klump (Murphy) has done his best to keep Buddy (his alter-ego) buried in his subconscious. Unfortunately, the portly shy professor is horrified to find him resurfacing in untimely outbursts, and threatening his plan to marry his colleague, Denise Gains (Jackson). Using 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.
