Beware of Dog
Upon entering the little country store, the stranger noticed a sign
saying "DANGER! BEWARE OF DOG!" posted on the glass door. Inside he
noticed 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 couldn't help but be amused. "That certainly doesn't 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."
