Beware of Dogs!
Upon entering a little country store, a stranger noticed a sign reading, "Danger! Beware of Dog" posted on the glass door. Inside, he noticed a harmless old hound dog asleep on the floor besides 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."
