The ex-Saturday Night Live star — famous for her stuffy Martha Stewart — lets loose as Mae Coleman in the movie musical Reefer Madness, a blood-soaked cautionary tale that she calls ''Roger Corman and Mel Brooks and Andrew Lloyd Webber meeting in one big hell party.'' Sure, kids, drugs are bad — but her performance is revelatory. Here are three things we (and you?) didn't know the 38-year-old star could do.

She sings. . .for real
''I was a voice major for a year, but I lost my way through the sordid life of a comedian.'' (Next up: She heads to Chicago to play Elphaba in Wicked.)

She vamps it up
''It's fun to play slutty people. Everybody thinks I'm 50 from SNL, 'cause I played so many old ladies.''

She swings a mean hoe
''I had to rehearse, constantly, with that friggin' bow stick. I don't think that I've ever worked so hard in my life. Whacking myself in the head and face.''
