Old Age!!

You ever been guilty of looking at others your own age and thinking, surely
 I can't look that old? Well.....you'll love this one!
 My name is Alice Smith and I was sitting in the waiting room for my first
 appointment with a new dentist.  I noticed his dental diploma, which bore
 his full name.
 Suddenly, I remembered a tall, handsome, dark haired boy with the same name
 had been in my secondary 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 far too old to
 have been my classmate.
 After he examined my teeth, I asked him if he had attended Morgan Park
 secondary school.
 ”yes, yes I did. I'm a Morganner! 'He beamed with pride.
 'When did you leave to go to college?' I asked
 He answered, “in 1965”.  Why do you ask?
 'You were in my class!' I exclaimed.
 He looked at me closely.
 Then the ugly,
 old,

 bald,

 wrinkled,

 fat arsed,

 grey haired,

 decrepit,

 bastard asked..
 'WHAT DID YOU TEACH?'
