An evil genie captured a Brunette, a redhead, and a Dumb Blonde and banished them all to the desert for a week. The genie allowed them each to bring one thing.

The brunette Brought a canteen so she wouldn’t die of thirst.
The redhead brought an umbrella so she could keep the sun off.
The dumb blonde brought a car door, so if it got too hot out, she could just roll down the window!
