Stupid Blonde Joke

3 girls, a blonde, a redhead, and a brunette, were driving in a car and ran outta gas in a desert. They all thought of ways to survive. So the brunette said, I’ll go look for food in case we get hungry. The redhead said, I’ll look for water in case we get thirsty. And then the blonde went out to look for something and came back with the car door. She said: We can roll down the windows in case we get hot!
