The funniest thing I did (in my opinion) was attempt to hypnotise (covertly) a fellow student, who was extremely stingy, to give me a chocolate(s)... This is someone that would not give away money to save someone's life..
When I told him about it at a later time, he had no recollection of it at all. That was a fun experiment.
I may very well be the only person at school that can manipulate someone covertly into performing minor tasks (Not that I make a common practise of it :P).

In reference to what code1949 said, someone in year 8 science managed to light a fire proof mat on fire (oddly enough, the non-fire proof bench did not catch fire, neither did the wooden shelves above it :/)

My maths teacher called a pupil gay once...

LOL
A couple years ago. my math teacher had a triangle that said "Find X". You know, a Pythagreum Teory one? I circled the X on the line and put "Here it is." Got full credit for it.

Today my history teacher said, "Fold up your pants and put them in your books."

Not really exiting but when i was still in school we had a 3 story building where the classrooms were.the school building had 2 large brick pillars that were used for hanging a large flag or something like that.when i first transferred to that school i noticed that some of the bricks were missing and the brick holes were filled half with a piece of wood each all the way to the top for some odd reason.one day when we had to switch classes from the bottom to the top i actually saw a few guys climbing it all the way to the top.usually it would take us 10minuts to get to the top because of all the students but these guys got there in under 2 minutes.

I never climbed the thing myself but that was really something that made the school unique for me.

Funniest moments in my classroom:
-- Multiple times when someone was running after someone else and they tripped
-- One time I was acting stupid, held on to a classmate's shoulders and he tried to run and get me off him, he made a sharp turn right and sent me into the wall
-- Some guys threw another guy out the window
-- We had to made dialogues of the kind "Who's he? He's [name] Is he [nationality]? No he's [nationality] What does he do? He's a [what he does] Where does he come from? [Country]" and I wrote my dialogue like this:
- Who's this?
- - Marvin the Martian
- Is the Dutch?
- - No, he's Martian.
- What does he do?
- - In one show, he leads the martian armada.
- Where does he come from?
- - Not sure, either mars or the mind of the cartoonist who drew him.
