While waiting for my first appointment in the reception room of
a new dentist, I noticed his certificate, which bore his full
name. Suddenly, I remembered that a tall, handsome boy with
the same name had been in my high school class some 30 years
ago. Upon seeing him, however, I quickly discarded any such
thought. This balding, gray-haired man with the deeply lined
face was too old to have been my classmate.

After he had examined my teeth, I asked him if he had attended
the local high school.

"Yes," he replied.

"When did you graduate?" I asked.

He answered, "In 1964."

"Why, you were in my class!" I exclaimed.

He looked at me closely and then asked, "What did you teach?"
