The going logic, as we near the end of the calendar year, is that Rebecca Black's "Friday" was the worst video of 2011. Heck, NME.com actually declared it the worst video OF ALL TIME. But we here at Yahoo! unearthed a few videos that actually made "Friday" (which, granted, did place pretty high on our 2011 Worst Videos list) look like Peter Gabriel's "Sledgehammer" or Michael Jackson's "Thriller." And unlike young Rebecca, the artists behind those other terrible 2011 videos--actual adults--had no excuse. They were old enough to know better.

Check out the videos below and try to have fun, fun, fun, fun...but you have been warned. They're BAD. Clockwork Orange-style eyeball-cufflinks are recommended to help you get through all 10 clips.

10) Countess LuAnn - "Chic C'est La Vie"

Following up the viral success of "Money Can't Buy You Class," this Real Housewife of New York once again proved that money can't buy you a decent song or music video, either. And all the money in NYC apparently still couldn't buy enough AutoTune to render this lady listenable.

9) George Michael - "True Faith"

George Michael and New Order were two of the great British pop acts of the 1980s. So news that George would be releasing a cover of the New Order dance smash "True Faith" to benefit Comic Relief 2011 seemed like an exciting development...except for the sad fact that George's Comic Relief effort turned out to be, well, comically bad. We're not sure what was worse about it: the fact that he slowed down New Order's BPM by about 97 percent, that he saturated his robotic recording with enough AutoTune to make even Countess LuAnn balk, or that the entire video took place in the clouds so that it resembled an outtake from Eddie Murphy's box-office flop Holy Man or a Philly Cream Cheese commercial. Regardless, this abysmal video was enough to make us lose faith in British pop music altogether.

8) Emii - "Stilettos"

With this video, Gaga wannabe Emii sent all potential boyfriends a clear message: love her, love her stilettos. Fair enough. But love this video and song? Well, that was asking way too much. This really is a video probably only Imelda Marcos could love.

7) Inessa Lee - "Take Me To The Moon"

"American Idol" fans may recognize Inessa as the Ukrainian auditioner from Season 10 whom Steven Tyler lasciviously called a "little spitfire." But it seems Inessa prefers to be known as a "singing doll," according to her delusionally entertaining website. "Her emerald green eyes attract you. Her angelic voice makes you shiver...Her name is Inessa, and her music style is pop electronic, with a resemblance to Shakira, Ke$ha, and Kylie Minogue. Inessa is a singing doll: Innocent and sexy at the same time," reads her wildly hyperbolic bio. "Singing doll Inessa is a complete package: In addition to her exceptional beauty and talents, she is a singer and songwriter. The world has been waiting for her!" Honestly, she could have kept the world waiting a lot longer. This is not good.

6) Kalup & Franco - "Rising"

In between sleepwalking his way through his Oscars hosting gig or guesting on "General Hospital," James Franco somehow found time to start a psychedelic band, Kalup & Franco, with Brooklyn-based performance artist/drag aficionado Kalup Linzy. Their resulting music video looked like something that was shot on "General Hospital" set...in 1977. With a Fisher-Price camera. That was then played on a secondhand Betamax VCR. It was assumed by many viewers that the new-agey, public-access-TV visuals behind His Highness's video were purposely created to look cheap and cruddy...but you know, we're not so sure. A better explanation? It's possible that whatever James was suspected of smoking when he hosted the 2011 Academy Awards was also in this video's director's pipe when this confounding clip was shot.

5) Tonje Langeteig - "I Don't Wanna Be A Crappy Housewife"

While we appreciate this Norwegian pop wannabe's independent spirit, we're not exactly sure a video like this was what Gloria Steinem, Betty Friedan, or even Helen Reddy had in mind when they crusaded for women's equality. Tonje merely demonstrated here that women are just as likely to make a terrible music video as men, and just as untalented as their YouTube brethren. And really, we don't think she needs to be worried about becoming a crappy housewife, because this video is embarrassing enough to scare away marriage-minded potential suitors well into the new year.
