Who's going the wrong way

  There was an old man who was driving his car home on the highway, and suddenly the phone in his car rang.  It was his wife calling him, and she said, "Hey John, I'm sorry to disturb your driving, but you know what? A report on the raido said there was a crazy man driving the wrong way on the highway. So please be careful, OK?" And the husband said, "Oh, yes! But it's not just one person; there are hundreds of them!"
