I was sitting in the waiting room for my first appointment with a new dentist. I noticed his dds diploma on the wall, which bore his full name. Suddenly, i remembered a tall, handsome, dark-haired boy with the same name had been in my high school class some 30-odd years ago. Could he be the same guy that i had a secret crush on, way back then? Upon seeing him, however, I quickly discarded any such thought. This balding, gray-haired man with the deeply lined face was way too old to have been my classmate. After he examined my teeth, I asked him if he had attended northmont high school.
'Yes. Yes, I did. I'm a thunderbolt,' he gleamed with pride.
When did you graduate?' I asked.
He answered, 'in 1975. Why do you ask?'
You were in my class!', I exclaimed.
He looked at me closely. Then, that ugly, old, bald, wrinkled faced, fat-ass, gray-haired, decrepit son-of-a-bitch asked, 'what did you teach?'

Hilary Koprowski

Died 11 Apr 2013 at age 96 (born 5 Dec 1916).Polish virologist and immunologist who discovered the first vaccine against poliomyelitis which was based on oral administration of attenuated polio virus. In researching a polio vaccine, he decided to focus on the use of live viruses that were attenuated (rendered non-virulent) instead of the killed viruses that became the basis for the injections created by Jonas Salk. Koprowski viewed the live vaccine as more powerful since it entered the intestinal tract directly and could provide lifelong immunity, whereas the Salk vaccine required boosters. Also, taking a vaccine by mouth is easy, whereas an injection is more expensive and needs medical facilities. It was taken by the first child on 27 Feb 1950 and within 10 years was used for immunization on four continents.
