Doritos fans gear up to submit homemade ads for this year's "Crash the Super Bowl" contest, where one fan finalist will have the chance to see his/her ad air during the Super Bowl XLVI broadcast.  

Doritos fans better get their game faces on, as they have less than two weeks to submit homemade ads for this year's "Crash the Super Bowl" contest, where one fan finalist will have the chance to see his/her ad air during the Super Bowl XLVI broadcast and win a guaranteed opportunity to work on a future Doritos project with The Lonely Island, an American comedy troupe that consists of Andy Samberg, Akiva Schaffer and Jorma Taccone.  

The Lonely Island will also create a Doritos ad that will air during the Super Bowl XLVI broadcast, going head-to-head with the winning consumer-created spot.

If the consumer-created Doritos ad scores No. 1 on either the USA TODAY ad meter-which tracks the second-by-second responses of a panel of viewers to ads during the national broadcast of the Super Bowl and ranks them favorite to least favorite-or the USA TODAY Facebook Super Bowl ad meter-which allows consumers to view and vote on the ads, its creator will win a $1 million bonus. Should The Lonely Island score No. 1 on either ad meter, Doritos will donate $1 million to the Berkeley Unified School District, Berkeley, Calif.

Consumers are encouraged to upload their 30-second commercials to www.crashthesuperbowl.com by Nov. 21. The site also houses a toolbox where Doritos logos, product shots, pre-licensed music and animations are available for download and use. In addition, the site is loaded with tips on creating a winning Super Bowl ad from last year's Crash the Super Bowl winners, JR and Tess Burningham, who serve as special advisers to contest entrants.

Doritos tortilla chips are produced by Frito-Lay North America, Plano, Texas.
