Car-door Jokes

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!"
