The Nutty Professor (1996)

"Inside Sherman Klump, a party animal is about to break out."

When beautiful Carla Purty joins the university faculty, genetic professor Dr. Sherman Klump grows desperate to whittle his 400-pound frame down to size and win her heart. So, with one swig of his experimental fat-reducing serum, Sherman becomes 'Buddy Love', a fast-talking, pumped-up, plumped down Don Juan.
