true story.  just the other day I heard the local PD dispatched to a broken window on an automobile.  seems that Beavis and Butt-Head were trying to get into Beavis' car and the key wouldn't work.  so Butt-head, being Butt-Head, suggested that Beavis just break a window to gain entry.  Beavis complied.  then and only then did Beavis realize that this wasn't his car.  I give them credit for reporting it to the local police rather than scampering away.
