One of my favorite HS teachers used to refer to us as slackers or turds, but it was an honest term of endearment. When Gattica came out, he promised 10 extra points on our next test if we brought our ticket stubs in, it was a Biology class.

In 5th grade I called one jackass of a teacher an "idiot teacher" to a friend of mine who didn't cover my ass to let me know said teacher was within ear shot. I got a slap on the wrist, but the teacher was VERY defensive about the remark.

One of the few jerk teacher things I remember while going through the public education system was middle school orchestra. Our teacher said we had done too much work not to have our parents attend the next concert and watch us, and that any student who didn't bring their parents to the performance would receive a D as a test grade, no exceptions. Long story short, I got the D.

One last thing was in HS Spanish, we were learning how to order things in a hotel and one of the questions on an assignment was to write how to order rooms for certain guests (handicapped, family of four, etc.) One of the questions was what a pair of newlyweds would tell the clerk. The correct answer, according to the teacher's edition, was to ask for a room with TWO beds. Despite our protestations, he graded us strictly by his book's answer.

A mutual friend of Atmanryu and I is of Eskimo descent and had one despised teacher (by the whole class) who would constantly call him a "Damn Jap." Eventually the parents of the kids in the class got together and decided to hold daily watches, so that the teacher had to act normal and respectful all the time until she ultimately left/transferred/quit.
