Desert
A blonde, a brunette, and a redhead were lost in the desert. They were driving around in a Jeep when it broke down, because they had nothing else they decided to each take a piece of the Jeep as they continued their journey. The brunette took the radiator, the redhead took the seat, and the blonde took the door.
After a while of walking the redhead asked the brunette "I'm confused, why did you bring the radiator?"
The brunette responded, "If I get thirsty,I can drink the fluid."
Next the blonde asked the redhead "Why did you bring the seat?"
So the redhead said "If I get tired,I am not going to sit on the sand. I can sit on this comfortable seat."
Finally the brunette asked the blonde why she had chosen the door.
The blonde quickly responded to this question, "Well, when I get hot all I have to do is roll down the window."
