Joke

I was driving down a lonely Colorado country road one cold winter day when it began to sleet pretty heavily. My windows were getting icy and my wiper blades were badly worn and quickly fell apart under the strain. Unable to drive any further because of the ice building up on my front window I suddenly had a great idea. I stopped and began to overturn large rocks until I located two very lethargic hibernating rattlesnakes. I grabbed them up, straightened them out flat and installed them on my blades, and they worked just fine.

What! You've never heard of... wind-chilled vipers??
