### Good thinking

Two brunettes and a blonde are driving in the desert when, all of a sudden, their car breaks down.

The first brunette takes some food in case she gets hungry, the second brunette takes some water in case she gets thirsty and the blonde takes a car door.

When questioned about her choice, the blonde replies:

"Well, if I get hot, I can roll down the window!"
