You may have heard of him -- he's kind of like a streaker, only he stops and leaves his mark.

The famed "Butt Bandit" has been giving the good people of Valentine, Neb., a good look at his hindquarters for over a year now. The man, who strikes on random nights, skips from one business to the next in the town of 2,650, pressing his greasy rear -- sometimes even his groin -- against storefront windows, leaving an imprint. Store owners and church employees have reportedly had to clean petroleum jelly and lotion off of the windows he's smeared with his cheeks. Not surprisingly, residents say they're pretty grossed out when they come upon these spots.

Police Chief Ben McBride calls the case the "weirdest" he's ever seen, but says he's worried about the "next step." After taking a break for many months last year, the Bandit resumed his activities this summer. "People said he was done," McBride said. "Then he started back up this summer." He reportedly imprinted the windows of a hotel during a recent escapade.

We should note that his nickname is a little misleading, as he never steals anything, except the unblemished innocence of the little town of Valentine.

Below are some bandits of the photobombing kind ...
