American Idol finalists David Cook and David Archuleta take on Tom Cruise.

It's an iconic slice of movie history, a young Tom Cruise rocking out to "Old Time Rock and Roll" wearing only a dress shirt, tidy-whities and white socks in "Risky Business." That one scene has been copied and parodied millions of times and now its popped up as a brilliant commercial for Guitar Hero starring both David Cook and David Archuleta of "American Idol."

What's really interesting about the two takes of the commercial are the difference between the boys -- differences that I say, prove that the right one took home the prize.
