On the door of the general store, a customer noticed the sign DANGER! BEWARE OF DOG! He carefully entered the store, but once inside all he saw was a harmless old hound dog asleep on the floor beside the cash register. He asked the store manager, “Is THAT the dog folks are supposed to beware of?”
“Yep, that’s him,” he replied.
The stranger could not help but be amused. “That certainly does not look like a dangerous dog to me. Why in the world would you post that sign?”
“Because,” the owner replied, “before I posted that sign, people kept tripping over him.”
