Megan Fox taking a bubble bath? Not a terrible start to a commercial. What made the Motorola spot even more interesting was that they had to bring in a double -- for the actress's thumbs. Fox suffers from brachydactyly, a condition that results in clubbed thumbs.
Jay-Z for Budweiser
For Budweiser Select, the company brought in football royalty Don Shula to square off against one of rap's biggest stars. The two played a confusing-to-follow, futuristic, holographic football game that was shown on one of Hova's flat-screen TVs. It's good to know that even in the future, Jay-Z is still the coolest guy in the room, and two-time Super Bowl champ Shula is as competitive as ever.
Britney Spears for Pepsi
In 2002, Pepsi wanted to showcase its generations of fans, so they had Spears -- at the peak of her popularity -- step into ads set in 1958 and the intervening years up to the present. The black-and-white spot of Spears singing and dancing in a soda fountain kicked off the night of commercials. (Full disclosure: Yahoo! teamed with Pepsi to promote the ads.)
Justin Timberlake for Pepsi
In 2008, Pepsi got another former Mouseketeer in an ad, using the singer/actor/beloved "Saturday Night Live" host to promote Pepsi Stuff. The spot found Timberlake being pulled across town by a mysterious force and incorporated a whole lot of physical comedy and cameos by Andy Samberg and Tony Romo.
Eminem and Clint Eastwood for ChryslerChrysler went for a combination of grit and class in 2010 with "Imported from Detroit," as Eminem drove through the Motor City, eventually joining a gospel choir onstage as they sang the opening notes of "Lose Yourself." Two years later, Chrysler again had a unique take, this time with Eastwood discussing how it was halftime in America. The Eastwood ad generated a lot of interest, angering Karl Rove and spawning an "SNL" parody.
