For a town obsessed with caloric intake, Hollywood sure loves to get big. Ever since ''Weird Al'' Yankovic waddled around in ''Fat,'' his 1988 parody of Michael Jackson's ''Bad,'' a parade of svelte stars has donned prosthetic fat suits for laughs. (But not Brad Pitt, who'll play a former heavyweight in the Nov. 22 episode of Friends.) Here's where some other faux fatties land on the scale of good humor.

HIGH POINT-LOW POINT [10-1]

FEBRUARY '96 [7]In a surprise prom-night Friends flashback, Courteney Cox Arquette's Monica balloons up wider than a latter-day Matthew Perry.

JUNE '96 [9]Audiences howl at Eddie Murphy's The Nutty Professor, as the flabulous Klump family makes a flatulent first impression.

JUNE '99 [5]Ewww! In Austin Powers 2, Mike Myers' slobby Fat Bastard ups the quease factor, hiding leftovers in his greasy fat folds.

JUNE '00 [3]It's deja vu for moviegoers as Martin Lawrence -- looking like a Klump reject -- licks all the plates clean at Big Momma's House.

JULY '01 [6]Oscar darling Julia Roberts is the next thin thesp to hit the trough, playing against type as a former fatty in America's Sweethearts.

NOVEMBER '01 [4]Another Oscar winner, skinny Gwynnie Paltrow, plumps up to 300 pounds in Shallow Hal -- and legions of Jenny Craig fans roll their eyes.
