Britney, K-Fed, Hilton Sisters Top Dirty List

Sex tape star Dustin Diamond, a.k.a. Screech, is a dirty, dirty son of a b!tch. But when it comes to housecleaning, well, the man who doled out the Dirty Sanchez on film didn't fare as poorly as some other celebrities.

In a national survey commissioned by Cascade dishwashing detergent, people were asked which famous couple they imagined would be the best -- and worst -- at taking care of their own homes.

Nice, but kinda boring Sarah Jessica Parker and Matthew Broderick were voted the cleanest celebrity couple and received 69 percent of the votes.

TomKat was a distant second with nearly 9 percent, with Ashton Kutcher and Demi Moore behind them with 7.5%.

On the other end of the spectrum, we have the amazing Britney Spears and Mr. Britney Spears, a.k.a. K-Fed. They finished dead last, as fans apparently believe they live in a sty. We can't verify that, but it wouldn't surprise us.

K-Fed is essentially a walking sty. Can you see that douche contributing anything as far as chores? Or to society in general? T.H. Gossip cannot.

Really, though, who the hell knows what f*%ked up $h!t goes down behind those Malibu walls. Oh, if little Sutton Pierce could talk...

The survey didn't bode well for the Hilton sisters either. When asked which celeb duo they would enlist to clean their homes, respondents chose skanky Paris and Nicky Hilton -- dead last.

Unfortunately for the heiresses, top-notch maid services (or other kinds of intimate "servicing") weren't taken into account. Which is too bad, because they'd surely do better in that poll.
