We love Xeroxing our naked butt as much as the next gal, but a vandal in Valentine, Nebraska is taking the prank to a whole new level.

Last year, a pair of greased butt cheeks were found smeared on the window of a local Methodist Church. Since then, the Vaseline-slicked vandal -- termed the Butt Bandit by town residents -- has been leaving his mark on the windows of businesses all over the city. The town's only clue to the culprit's identity is a grainy surveillance video, which reveals that he has a dark complexion and hair styled into a "1980s feathered look," according to cops.

A few residents are amused by the shenanigans, but police chief Ben McBride is worried about the bandit's "next step." (Which would be what exactly?) And us? We think those lotioned butt cheeks might just be high art.
