Bud Light's spot featuring a crotch-biting mutt ranked as the most popular Super Bowl commercial, according to USA Today's annual ad meter contest. The 136 adults polled also gave high marks to Pepsi's ad, in which a bear disguises himself as his human owner, and Frito-Lay's spot featuring Grandma and Grandpa fighting over a bag of chips. Surprisingly, no one seemed to like FedEx's alien office worker ad — which was my personal favorite. Eh, what do I know.
