A friend of a friend of mine was sitting on a lawn sunning and reading, when he was startled by a fairly late model car crashing through a hedge and coming to rest on his lawn. He helped the elderly driver out and sat him on a lawn chair.

"My goodness," he exclaimed. "You are quite old to be driving!"

"Yes," he replied. "I am old enough that I don't need a license anymore. The last time I went to my doctor he examined me and asked if I had a driving license. I told him yes and handed it to him."

"He took scissors out of a drawer, cut the license into pieces and threw them in the wastebasket. 'You won't be needing this anymore,' he said."

"So I thanked him and left."
