Commercial: Best Buy (2011)

The last time anyone paid attention to Ozzy Osbourne was when he was spewing gibberish on his MTV reality show The Osbournes. With wife Sharon and daughter Kelly making moves on the television circuit, it looks like Ozzy's celebrity status us taken a bigger plunge than son Jake during his rehab stint. In an attempt to get back into the limelight, he agreed to poke fun at his senility and play second fiddle to Justin Bieber in a Best Buy Super Bowl ad that parodied the mobile high-speed craze. Just when you thought the Oz couldn't make himself look even more foolish, he pulled a Britney and did it again.
