Win a Tide-themed iPod

If you watched last weekend's Super Bowl (the height of American Football), you probably saw Tide's "Talking Stain" ad. It was one of the better ones; a man trying to conduct an interview is distracted by a nagging stain on the interviewee's shirt.

Today, Tide has launched a contest encouraging people to make their own "mocking stain" ads. Among the prizes are 34 limited edition Tide-themed iPod Classics. The size isn't listed, but they're described in the official rules as having a value of $300US, so we assume it's the 80GB model.

This isn't the first time Tide has released a special iPod. Last year, they gave away orange nanos in conjunction with the St. Bernard Project in New Orleans. This got us thinking about other limited edition iPods we've seen.

• In 2006, French radio station Nostalgie gave away 100 limited-edition Michael Jackson iPods

• Two years ago, the Japanese company RUN'A sold 1,000 "Snoopy" iPod nanos

• Last September, Target (a discount department store in the US) sold pink iPod Shuffles to support the Breast Cancer Foundation

• Finally, who could forget the granddaddy of special iPods, the U2 model.

Good luck making your stain ad, and let us know if you win one of these.
