I don\'t know...nothing that creative here. Let\'s see...
There are a few teachers we call by their first names, such as my English teacher, Mrs. Smith. We call her Alida.
I had a Chem teacher the last two years named
Mr. Gunner. We always simply called him Gunner, or Gunner-Man. He was an alcoholic though, and although he was my favorite teacher I ever had, he would be out a lot. Our usual sub was Mr. Parker, who looked kinda like Gunner, only cleaner. We usually called him Clean Gunner, or simply CG.
Then I had a technology teacher named Mr. Peters. Most people call him P Diddy now though

That guy was great.
