Upon entering a little country store, a stranger noticed a warning sign that read: “Danger! Beware of dog!” posted on the door. Inside, he noticed a harmless little dog asleep on the floor beside the cash register.

“Is that the dog folks are supposed to beware of?” he asked the owner. “Yep, that’s him,” came the reply.

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 explained, “Before I posted that sign, people kept tripping over him.”
