Once there was a blonde, a brunette, and a redhead. They all had to go to the desert and take one thing.

The brunette took a water bottle, the redhead took an umbrella and the blonde took a car-door.

They were walking in the desert with their objects and 3 men came up to them and said to the Brunette, "why have you got a water bottle?" The Brunette replied," To drink water!"

They asked the redhead,"why do you have an umbrella?" She said,"Because if it gets hot I can have some shade."

Then they asked the blonde," Why do you have a car-door?" She replied," If it gets hot all I have to do is roll down the window!"
