The whole bikini-car-wash thing has been done again and again. However, the folks at "Attack of the Show" and the 501st Legion in Los Angeles were able to add an out-of-this-world twist to the sexy staple by having their well-proportioned washer girls dress like slave Princess Leia.

As an added bonus, "Attack of the Show" co-host Sarah Jean Underwood used her whole body to join in on the scrubbing.

The charity event raised $1,000 dollars for the Make-A-Wish Foundation. Read on to check out a video of the intergalactic fun.
