A judge was punishing three men because they had committed a crime. Their sentence was a few years in the desert. He said that they could each take one thing with them.

The first guy decides to take an umbrella, so that he can have shade whenever he wants.

The second guy decides to take a water bottle so that he won't get thirsty.

Finally, the third guy decides to take a car door.

The judge asked, "Why in the world would you want to take a car door?" The man replies, "Just in case it gets hot, I can roll down the window."
