A wildlife safari in Oregon has come up with an unusual way to raise money in the tough economic climate.

For $20, visitors can have their car washed by the zoo's elephants, who scrub with sponges and rinse with their trunks.

Wildlife Safari Executive Director, Dan Van Slyke, and Elephant Supervisor, Carol Matthews, claim that the elephants don't mind the work, and that the fundraiser has been a hit.
