<P> After the fall out with Carla, Richmond not only fires Sherman, but gleefully tells him that Buddy will be taking his place at the Alumni Ball . Sherman sees a taunting videotape from his alter ego and decides he has had enough of Buddy, taking the decision of destroying all of the serum samples, which he does with Jason's help . Sherman plans to set things right with Carla and get the grant from Hartley . Unfortunately, Buddy knew that this would happen and prepared himself by hiding a sample of the serum in one of Sherman's diet shake cans, which Sherman drinks, causing him to transform into Buddy again . Jason tries to stop him from going to the ball, but Buddy knocks him out with a single blow to the face and departs . </P> <P> At the ball, Buddy demonstrates the effects of the serum to the audience, but Jason arrives in time, as he has found out that Buddy's testosterone levels are at a lethally high 60,000% . Buddy plans to drink a large sum of the potion to get rid of Sherman for good; Jason knows that if he drinks it, it will kill Sherman and possibly Buddy . The two of them get into a brief fistfight, but Sherman begins to fight Buddy from within . Sherman eventually transforms into his regular self and admits his misdeeds to the shocked audience, including his parents; he says that Buddy was who he thought he and everybody else wanted him to be, and that he should accept himself for who he is . As he leaves, Carla stops him and asks why he lied; he says he did not believe that she would accept him . While they don't initiate a romantic relationship, Sherman and Carla remain friends and share a dance together . Richmond rehires Sherman and Hartley gives the donation to Sherman because he is "a brilliant scientist and a gentleman ." </P> <Ul> <Li> Eddie Murphy as Professor Sherman Klump / Buddy Love <Ul> <Li> Murphy also plays Papa Cletus Klump (Sherman's father), Mama Anna Klump (Sherman's mother), Granny Ida Jenson (Sherman's Grandma, Anna's Mama), Ernie Klump, Sr. (Sherman's brother) and Lance Perkins, a parody of Richard Simmons </Li> </Ul> </Li> <Li> Jada Pinkett as Carla Purty </Li> <Li> James Coburn as Harlan Hartley </Li> <Li> Larry Miller as Dean Richmond </Li> <Li> Dave Chappelle as Reggie Warrington <Ul> <Li> Chappelle reprised his role on Chris Rock's 1997 album Roll with the New . </Li> </Ul> </Li> <Li> John Ales as Jason </Li> <Li> Jamal Mixon as Ernie Klump, Jr . </Li> <Li> Montell Jordan as himself </Li> </Ul> <Li> Eddie Murphy as Professor Sherman Klump / Buddy Love <Ul> <Li> Murphy also plays Papa Cletus Klump (Sherman's father), Mama Anna Klump (Sherman's mother), Granny Ida Jenson (Sherman's Grandma, Anna's Mama), Ernie Klump, Sr. (Sherman's brother) and Lance Perkins, a parody of Richard Simmons </Li> </Ul> </Li>
