For years and years, I thought the little Healthy Choice logo was a woman in an evening gown, which I never quite got the significance of healthy TV dinners to. It's only fairly recently that I figured out it's actually a jogger (which makes a hell of a lot more sense). In my defense, the way the logo used to be, the legs sort of melded together and it looked at least a little like a woman in a flowing/billowy sort of gown as she goes up some stairs or something. The logo now has the legs much farther apart so that its obvious that it's a jogger.
What stuff did you always thought you knew, but it turned out you were completely wrong and look back in embarrassment that you never got it? Share, please, so I don't feel such a fool about the jogger thing!
