Just saw John Waters' latest movie, "A Dirty Shame," on DVD and while Waters has certainly made funnier movies ("Serial Mom," "Cry Baby"); dirtier movies ("Pink Flamingoes," "Female Trouble") and better movies ("Hairspray," "Pecker") he certainly hasn't made a worse one than this (though "Cecil B. Demented" was pretty bad). The "story" (and I use the word very loosely) of a woman who endures a concussion-induced sex-addiction, "A Dirty Shame" stars the usually brilliant Tracey Ullman, the always sexy Chris Isaac, the perpetually stupid Johnny Knoxville and what-the-hell-is-she-doing-in-this-movie-? Selma Blair.

Ullman is Sylvia Stickle, who runs a convenience store with her husband, Vaughn (Isaac) while watching over her daughter, Caprice (Blair) who is under house arrest for public lewdness. Blair wears outrageously over-sized prosthetic breasts and dances in bars under the screamingly unfunny pseudonym of Ursula Udders.

When Sylvia is hit in the head by a passing lawn-mower handle in the single most contrived scene ever filmed, her inner libido is unleashed and she suddenly becomes the 12th Apostle in Knoxville's sexual "church" (this after Knoxville performs oral sex on her in the middle of a busy intersection).

Other than coming up with some funny new phrases for various sex acts ("yodeling in the canyon" was my favorite and the funniest), Waters just gives us a one-joke movie that wears very thin about halfway through. Waters regulars Mink Stole and Patty Hearst appear, as well as the very funny woman who played "Mee Maw" in "Pecker." But even the CGI animated sex-addicted squirrels (yes, you read that correctly) seem nothing more than a car-insurance commercial rip-off. Occasionally, Waters literally states the obvious by super-imposing words like "W-H-O-R-E" or "E-R-E-C-T" over the action, which served no real purpose, other than to shout "gimmick!" over and over. Sadly, commercial success seems to have severely dulled Waters' edge, and that's the biggest dirty shame of all.
