Welcome to Ad Rant's 10-part series on The Best and Worst Celebrity Ads. In Part 1, we take a look at how some top stars earn millions for 30 seconds of acting as foolish as humanly possible. Where's the dignity?

You see, Hollywood stars are America's royalty. They have their reputations to uphold. They certainly wouldn't want their loyal subjects to think they'd sell out for a buck, and that's why the biggest names often refuse to appear in TV ads ... in America. Of course, they don't mind doing commercials in Japan. The idea is that no one in the U.S. will ever see these ads. Their secret will be safe.

Because, you know, there's no one in the U.S. with access to YouTube.
