In round three, Malcolm Turner's stepson Trent (Brandon T. Jackson) is nearly 18, and more interested in a career as a hip-hop artist than in going to Duke. This doesn't sit well with Malcolm (series staple Martin Lawrence), but the family debate gets put on hold when Malcolm's grind as an FBI agent evokes the wrath of Eastern Bloc baddies with moles in the agency. Malcolm and Trent have nowhere to hide except in '50s-dated drag at an all-girl arts academy, where Malcolm's Big Momma scores a post as a house mother while Trent's Charmaine cruises the campus with a perma-boner under his girdle. Gone are the fart jokes and the lovely Nia Long as Trent's mother/Malcolm's wife. Director John Whitesell, who helmed BM2, keeps the gender-flipping gags firing with a sense of seriousness that seems blind to the inanity of the granny-panty flimsy plot. The biggest laugh in the film comes from an uncredited Faizon Love as a janitor who wants to get on Momma's caboose bad.
