With my Geico customer post in mind, this week's "Show Off Your Smarts" challenge is to share your favorite facts related to advertising - print, television, radio, billboards, anywhere. I know there are some great facts about celebs who got their starts in ads, commercials that didn't translate well into other languages, ads that backfired, etc. So go ahead and make us all a little smarter by sharing your facts in the comments below.
