An elderly couple is taking a Sunday drive on I-80 when the wife gets a call on her new-fangled cell-phone. Her daughter is frantic, "Mom, there is a lunatic driving the wrong way down the road on I-80 near your house!" The wife turns to her husband and says, "Did you hear that? Some maniac is driving down the wrong side of the road!" The husband screams, "One lunatic?! There are hundreds of them!"
