As a stranger entered a little country store, he noticed a sign warning, “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.
“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!”
