Stupidity must be quantifiable. Some people have a demonstrably large amount of it. Today I saw a person trying to back out of her driveway onto a four-lane highway -- despite having a driveway long enough and unconstricted enough that she could very easily have turned around and come out front-ways. Because she was coming out backwards she was stymied by traffic that would not have been such an obstacle had she simply used some of that wasted gray matter taking up space inside her noggin.
