While the New York Giants were battling the New England Patriots on the field (the Giants won 21-17), another parallel struggle was happening off the field — the fight to create the most memorable Super Bowl commercial. At an average of $3.5 million a pop, the ads generally played it safe: big stars, nostalgic re-enactments, exploitations of the cute factor (read: puppies and babies).

Among the most buzzed-about was Clint Eastwood's "Halftime in America" ad for Chrysler, which has divided viewers who recognized it as either a step-up or a step-down from last year's Chrysler spot starring rapper Eminem. In this new ad, which aired during half-time, Eastwood gives a tough pep-talk to Americans. "This country can't be knocked out in one punch," the Million Dollar Baby director says in the video.

Another favorite comes from Pepsi, featuring Elton John as a tyrannical king who tempts performers with a Pepsi reward if they're able to entertain him. Enter American The X-Factor winner Melanie Amaro, who wows John and the crowd with her rendition of Otis Redding's "Respect." When John begrudgingly rewards Amaro's performance with a "Pepsi for you," Amaro stands up to him like a true Musketeer. "No, Pepsi for all," she says. Then Flava Flav for some reason appears.

Brazilian supermodel Adriana Lima really turned up the heat with a Teleflora.com ad. After sexily putting on a little black dress, stockings and red lipstick, Lima reminds her male viewers that Valentine's Day is coming up. "Give, and you shall receive," she says, tauntingly.
