Query: Flabby Humor

Martin Lawrence's take on Eddie Murphy's Nutty Professor movies (but without the refined tone and impeccable taste), this one has Lawrence as an undercover FBI agent who impersonates a fat old woman (with diarrhea) in order to nab a bad guy. Most of the humor is gross, toilet-level stuff, presented with lousy timing, but this essentially one-joke, dress-up movie does pack a few laughs. Lawrence does have some funny moves. Still, it's not Tootsie or or even Mrs.Doubtfire.
