It may sound wierd but the best way we found was to start humming. Yes humming, someone would start really low in one corner of the room and then everyone would join in slowly until it rose to the point the teachers couldn’t continue the lesson because it was so loud, you had to be there to hear it in action. Whirling around to confront us no obvious suspect would be available and everyone would be perfectly still and seated, the perfect crime if you will. So how did you annoy the techers who deserved it or how did you eliminate those considering a career in teaching?
We never really got our teachers mad at us, but we did like to have fun with them.
In 12 grade Physics, we decided to have some fun with the student intern who was teaching us that week. We decided to start casually passing our physics books up to this one kid’s desk. The kid would take the books and start piling them on his desk. Before the intern knew it, the kid had this whole stack of 27 books on his desk. What was even funnier than that was that the Physics teacher saw what was going on and was laughing his butt off during the whole thing.
Then there was the Spanish class I took. My friend C decided to have fun with our Spanish teacher. He had a friend who was heavy into electronics make a small electronic beeper that would sound off a very high pitched “Beep” eveyr 3 minutes. It was small enough to fit in a 35 mm film canister. C took this device and hid it in our Spanish teachers room before class started. As with most U.S. High Schools, classes usually take about 5 minutes from the time the bell rings to settle down, and this class was no exception, so our Spanish teacher didn’t know right away the beeper was there. But at the end of the hour, every time it would beep, she would start frantically looking around for it. We finally gave in and showed her where it was, and she promptly confiscated it.
(NOTE: This is the point at which we found out she was a fun teacher to have.)
We pleaded with her to give it back because we wanted to pull the same joke on our English teacher that afternoon. After mulling it over for a few minutes, SHE GAVE IT BACK as long as we promised to not tell the English teacher that she did, in fact, give it back.
I think I can safely say that my Spanish class was her most memorable class. 
I found a particularly good way of annoying one of my teachers. He was an American teaching in Calgary, Alberta… although primarily the PE instructor, for some reason he was also saddled with grade seven social studies. I used to drive him up the wall by finding appropriate passages in my little red book (yep, the infamous Quotations from Chairman Mao Tse Tung). His inability to respond to them used to result in him almost spitting in rage.
Ah, the good old days.
For half a year in HS we had a history teacher who was a vice principal, and really didn’t belong in the classroom. He would tend to look only at the students who paid attention while he was teaching, so we decided that we should take turns being the interested student for the class. So each class, after the first few minutes, one student would pay close attention, ask questions, nod at the important points, while one by one everyone else started doing other things - reading or whatever. The teacher ended up having a private tutor session with a different student every day.
the alka seltzer incident is still legendary at john c. fremont jr. high.
a bunch of us went into class with water in our mouths.and then we slipped alka sektzer tablets in.
the teacher thought we were all rabid. (fremont is way out in the sticks)
boy, did we get in trouble-we were using DRUGS!!!
but i don’t think my mom ever forgave me for it. the others ratted me out(they were my alka seltzers) and i was suspended for 3 days. but i don’t think the poor teacher ever lived it down.
Or perhaps rent the movie “Summer School”?
I had a habit of irritating my HS biology teacher. One day he had me sit in the storge room between the two biology classrooms (its fairly big half-room with windows, not a broom closet). Well, after about 10 mins I start to get board, so I start playing with stuf in the storage room. So I find this human skeleton and I start sticking the skeleton arm out the door while saying things like “NOW can I come out ?”. He then sent me to the office.
I also got a week of detention for giving a teacher the finger behind her back. She turned around and I quickly changed to a waving hand. Since my brother and his buddy were laughing uncontrollably, she wasn’t fooled.
