For the seventh year running, PepsiCo's(PEP) Frito-Lay division is holding a contest for freelance advertisers to see who can make the funniest Doritos ad. The contenders include a skit where a dad and his burly friends dress up like princesses to impress his young daughter, and another spot involves an enraged naked bear. The company has five finalists for its Crash the Super Bowl contest, where anyone and everyone can go online and vote for their favorite spot. The two most popular ads will air during the game.
