My wife and I used to watch FoxNews (back when it was actually somewhat conservative) and play a little game we called "liberal or conservative?" We would turn the sound off, and when they were preparing to introduce a guest, we would look at their face on screen and try to determine just from their appearance whether they were a liberal or conservative. We eventually got bored with it because we always got it right. It was too easy.
Don't tell me you can't judge a book by its cover.
