My principal in 1st and 2nd grade was called Mr. Guggins (pronounced Goo-gins), but he had a doctorate and insisted on being called Doccctor Guggins.
Fifth grade English teacher, Mrs. Bloomer.
Fifth graders can be easily amused sometimes. “Mrs. Bloomers bloomers!” <insert lots of tittering and teeheeing>
Some of my classmates renamed out bitchy 8th grade music teacher, Ms. O’Connel. Their version still started with “c” but ended in the word “hole”. I never called her that (don’t like the word), but I was more than happy to go along with the plan to ruin the play she forced up to preform, on tape, the last day of school…who knew that “Anything Goes” isn’t supposed to end with gun fire and the entire cast dead? For some reason she changed the play to Wizard Of Oz in the years after our class.
When we were in that grade we also had a long term sub in English, Ms. Sherman. She got married that summer, and moved with us to the middle school as a Sped teacher, and was then known as Mrs. Nunziado. Then she got divorced when we were in 10th grade, and married on of our Social studies teachers, becoming Mrs. Willis, when we were in 11th grade. But we never called her anything but Sherman (or “Shermy”) much to the confusion of everyone but those in our grade. A popular frosh question was “Why do the 11th/12th graders call Mrs. Willis ‘Sherman’?” 
It was 9th grade.
We had an English teacher named Mr. Sims. He seemed rather effeminate and was called Sister Mims behind his back.
Imagine our surprise when he brought his drop-dead gorgeous redhead wife along on a field trip, ( Reminds me now of that scene in Fast Times at Ridgemont High when the dorky teacher shows up at prom with his beautiful spouse. Or was it Dazed and Confused?)
My middle school had a science teacher named Richard Koch. Needless to say, he went by the name Dick, creating endless amounts of entertainment for 7th graders.
I had a math teacher named Peter Pullen. Great guy, though, so he never got any crap about his name that I remember.
Mr. Ruggles
Elementary music teacher.
Just remembered this one…we had a bio teacher in our high school named Mr. Seamon (pronounced “semen”).
Melinda Cool – my kids day care lady. Very nice lady.
Dr. Jeffery Zink – inorganic chemistry professor
Dr. Hyuk Yu – chemistry professor
8th grade math: Miss Omen a.k.a. EVIL Omen, Bad Omen, OMEN V: The Fattening
Not a teacher, but there’s a cop here named Officer Dillow which usually gets morphed into Officer Dillhole or Officer Dildo. Not to his face, of course
Third grade substitute teacher: Mrs. Belcher
<burps>
Seventh grade substitute teacher: Mr. Hoh
heeheehee!
10th Grade Social Studies: Harry Stump.
Damn you, yojimbo. We had a Mike Hunt too. He was a substitute that often taught math at the high schools in the area. It must have been even worse for him because he had evidently had a stroke or some other type of motor-skill reducing disability, so he walked erratically with a cane.
Uh, yeah. That was supposed to be “Damn you, yojimbo, for beating me to it.” I wish no harm, hellish or otherwise, upon you in a general sense.
Robin Trout - We called her bird fish.
Mrs. Burgert - Booger, Boogert, Boogie, etc.
Mrs. Allbaugh - pronounced by most kids as awbaw, quickly turned into all balls or something similar.
Mrs. Vowel - She taught English.
Mr. Martin - Rhymes with fartin…
Mr. Cox - Nothing needs to be said.
As for students, one guy with the last name of Hauf was often dubbed Jack.
A guy with the last name Fleming was often referred to as Flem, and we occasionally teased his girlfriend about having Flem in her throat.
A girl with the last name Moorehead was asked one time what her middle initial G stood for. Before she could answer, a good friend of mine said GIVES!
Mrs. Thigpen - 2nd or 3rd grade.
She made us say “Pig pen” the first day of class to hopefully get it out of our system. It largely worked.
Mrs. Glasscock - Great Biology teacher, but a really unfortunate name.
Mrs. Payne - Math. Name not entirely inaccurate.
Mr. Golightly - Band director. Just a funny name, I always thought.
I am sure there were others, but that is what I can come up with off the top of my head…
2 to add:
Substitute in Illinois: Mrs. Jacksack.
Music program director(?): Mr. Badsing.
Also, turns out “Lipino” looks like Oh, nipple! reversed.
Had a music (choir) teacher in 7th/8th grade - Mr Love - who had this annoying habit of peeping down your top, or would ask you to pick summat up for him so he could watch you bend over… What a perv.
My dentist was Dr Slaughter. Wonderful fella. Had a few classes with his son as well who always got grief for the name.
My primary school principal was named Mr Handcock
