There's a blonde, a brunette, and a redhead traveling through
the desert when their car suddenly stalls.

They all get out
of the car and, upon realizing that it's not going to start,
they each take one thing from the car.

The brunette takes a
bottle of water, the redhead takes a bag of food with her,
and the blonde takes the car door.

They begin to walk through the desert, and soon stop to rest.

At this point the blonde and the brunette turn to the redhead
and ask her why she brought the food.

She replies, "Well, in
case I get hungry I'll have something to eat. "

They all think this is pretty reasonable and then the redhead
and the blonde turn to the brunette and ask her why she decided
to bring water.

The brunette replies, "Well, in case I got
thirsty I'll have something to drink. "

They all decide that's
a good idea, too.

Finally, the brunette and the redhead turn to the blonde and
ask her why on earth she would take the car door.

She replies,
"Well, I thought if I got hot I could roll down the window. "
