Dancing Men

Walking to work this morning I saw a sign saying DANGER MEN WORKING OVERHEAD. I thought, Could that sign really say DANCING MEN WORKING OVERHEAD, but I read it wrong? In that part of town it would not be surprising to learn that dancing men were working overhead. Nobody would question it, or wonder about it at all, they would only walk past and think to themselves, Oh well, I guess those dancing men are working overhead again.
