A private preschool in Auburn, CA, has put up the sign above in an attempt to get parents to crash more frequently while they struggle to understand how anyone could make such a dumb mistake. But is it a mistake? No one really seems to know. It's almost impossible to believe it was an accident. And yet, intentionally misspelling the sign seems pretty pointless—if not also dangerous, since, if we've learned anything from the Internet highway, spelling errors contribute to road rage.
