A little old man told his wife, "I have to go to my doctor's appointment now. I'll see you later."
After he left, his wife sat down on the couch and watched television. A news report came on that someone was driving down the interstate highway in the wrong direction. Knowing that that was the route he would be on, she called to warn him, "Honey, there's a car going in the wrong direction!"
The husband replied, "They're all going in the wrong direction!"
