Sorry if you've heard this story before!
I live on a state highway, so there's usually roadkill somewhere. One day I saw a rattlesnake that had been ran over many times. Stretched out, it would have been about five feet long.
Anyways, a couple of days later, I was down at the barber shop getting a trim, and I mentioned it to the barber. He got real excited and asked, "How big around is it?"
I couldn't exactly figure out what he was asking or why, so I said, "It's flat!"
