A hunch.

Commuting: it's opened a whole new world of people-watching for me.

Today, I came across a guy in a teal PT Cruiser with a "Wicked Clown" bumper sticker, sporting a flavor-saver goatee, and smoking a cigarette.

I've got a hunch that I wouldn't have much in common with this guy. Not that I have anything against goatees or wicked clowns, and I may even be able to overlook the smoking, but c'mon buddy, a PT Cruiser?
