That's right, Sarah Palin is back. The people's prime time princess is launching a bus tour this weekend, and many are speculating that it's the unofficial beginning of her campaign for the White House.

Backing up that theory, Jimmy Kimmel announced on Thursday night that a new ad in support of Palin was already running in Iowa, home of the first important (and least accurate) electoral event of the campaign season. But there's something slightly amiss with this ad; something you can't quite put your finger on until you see who paid for it.
