Three men are in the desert when their jeep breaks down... They decided to split up to find some help. One of the lads, Jack, says ""I'm taking the radiator since it has water in it."" Another, Mike, says ""I'll take a hub cap, for shade."" They see their third friend, Greg, taking the door off. ""What in the hell are you doing, Greg?"" ""Well if it gets too hot, *I can always roll the window down*""
