A man, a woman and an Antartican were driving in the desert in a jeep when the car suddenly broke down. Since none of them had any car knowledge, they decided to walk.
Each of them decided to take one thing with them: the man took the food in case he got hungry, the woman took the water in case she got thirsty, and the Antartican took the car door.
When questioned about her choice, the Antartican said, "Well, if I get hot, I can roll down the window!"
