Three guys, one black, one white, one Polock; find themselves stranded in the desert. Concerned for their safety, they agree to split up to find resources to hold them over until their rescue. After some time they regroup and share what they've found. The white guy says he found a cave where they can take shelter. The black guy says he found a small oasis where there's fresh water. When it's the Polock's turn to share, he gets an ear to ear grin! He's holding a car door. The other two, somewhat confused ask the Polock why he has a car door. He replies; "Well, if it's ever too hot, we can just roll down the window!"
