An elderly lady was stopped for speeding. She was going 70 in a 40 mile-per-hour zone. The policeman asked her, "Why were you going so fast, ma'am?"
She said, "Sir, the sign back there said seventy."
"No ma'am," he replied, "That wasn't the speed limit sign. That was the highway sign. That's Highway 70."
"Oh, my goodness," she exclaimed. "I'm so glad you didn't see me on Highway 129!"
