Joke

Three women- a blonde, a brunette and a redhead- are riding through the desert on a dune buggy. About two two hours later their vehicle dies with no gas and they're forced to travel to their destination on foot, but they all agree to carry something with them. The brunette brings canteens of water. The redhead takes a large beach umbrella. The Blonde somehow rips off the car door. The redhead asks her, "Why did you take the whole car door?" To which the blonde replied, "So I can roll down the window in case it gets too hot."
