Once there was a blonde, a brunette, and a red head out in the desert driving, when their car broke down.
They decided they would hike to the next road so they wanted to take one thing each to survive on.
The brunette picks up a bottle of water and the red head says,
"Why would we need that?" and the brunette replies,
"In case we get thirsty we can drink some."
So the red head picks up a can of gas and the brunette says to her,
"Why would we need that?"
and the red head replies,
"Just in case someone picks us up we can use the gas if they are out."
So the blonde picks up a car door and the brunette and the red head look at her in suprise and say,
"Why would we need a car door?"
and the blonde replies,
"In case we get hot we can roll down the window."
