Please double checkly grammarly careful.

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.

"With people these days, we're pretty sure it was probably on purpose," one driver told the local news station, though the quality of his answer reminded us it might be good old fashioned unintentional stupidity after all.
