My dad's favorite joke 3 guys are driving through the desert when their car breaks down. They grab as much of their supplies as they can carry and start walking. The first guy turns to the second guy and says ''I brought all our food cause you can't grow anything in the desert.'' The second guy replies ''I brought all our water cause it doesn't rain in the desert.'' The third guy is slowly trailing behind. The two guys ask ''Hey what are you doing?'' Dragging the car door behind him the third guy shouts ''In case it gets hot we can roll the window down!''
