expedition

A blonde, a brunette, and a red head are to embark on an expedition in a ship.

While they are setting up their ship, the brunette gets off board and tells the other two that she's going to go home to get something for the trip. When she comes back she has a bottle of water, when the other two ask why she brought that she tells them "so, i can drink it."

The red head, too, goes home to get something, when she comes back she has a group of bananas, when she's asked why she brought that, she tells them... "so i can eat it."

The blonde decides that she should, too, get something for the trip. So, she goes, when she comes back she has a broken car door, when asked why she got a broken car door, she says....

"So when i get hot, i could just roll down the window."
