These are supposedly actual signs that have appeared at various locations across the United States and rest of the world.
Sign on a repair shop door: WE CAN REPAIR ANYTHING. (PLEASE KNOCK HARD ON THE DOOR – THE BELL DOESN’T WORK)
Sign at Norfolk farm gate: BEWARE! I SHOOT EVERY TENTH TRESPASSER AND THE NINTH ONE HAS JUST LEFT
Seen during a conference: FOR ANYONE WHO HAS CHILDREN AND DOESN’T KNOW IT, THERE IS A DAY CARE ON THE FIRST FLOOR
