When I was in my new dentist's waiting room, getting bored having nothing to do, I began to examine the mundane details to pass time. Then I noticed his certificate on the wall, with his full name on it.
Out of the blue I recalled a tall, good-looking lad with the same name who'd been in my high school class some 30 years ago. However, when I finally saw the dentist, I quickly dismissed such thought. This balding, gray-haired man with lined face was far too old to have been my classmate. After he had examined my teeth, I asked him if he had attended the local high school many years before.
"Yes," he replied.
"When did you graduate?" I asked.
He answered, "In 1967."
"Why, you were in my class!" I exclaimed.
He looked at me closely and asked, "What did you teach?"
