When the class settled in this big mouth named jordan yelled "EEWW! I could see hair in your hand in the overhead''. The teacher was so emberass. A few minutes later, while the teacher was lecturing, she said ''would you be mad if I throw pencil to your face?''. The teacher said ''No I would be laughing while writing a referral''. Then he said ''I would not be really mad, but I could charge you for assault. With the money, I use it for a new a truck''. All hour, the whole class was laughing

A few weeks ago, this kid waled around the entire day in his underwear. I was extremely surprised that he wasn't asked to put some pants on or kicked out or anything. XD

Probably when toni hid a a whole box of pencils under his man boob.

the day my freind threw a chair at the sub made me laugh soo hard

The day a substitute started trash talking my Algebra 2 teacher and she walked into the classroom (cough...nazi... cough)
ah...good times...

Either the time a kid locked himself in his own locker, that "krump off" me and my friend had against these two other kids, or any of the times we had a crazy sub who would rage if you asked her for a paperclip.

the day i quit highschool me and by bud's sitting back drinking beers in grade 12 i wouldn't have passed anyways

There was one time, where you can tie the principal for $1 per roll. I didn't even see it because I hate my principal. I'm glad he gets what he deserves.

My math teacher started giving us a lecture on how she hated her boyfriend's ex girlfriend and talked about it for about 10 minutes, and then the principle and assistant principle walked in and she stopped in mid sentence breathed in quickly and said "OK lets get back to the lesson" and we all were holding our breath and as soon as the principle left we all started laughing, and then she continued to talk about it.

Well one time, there was like this stupid kid in my class named Brandon or something, he just sang a Peanut Butter Jelly Time in the line during the fire drill and then my teach came to him and say "Shut the f*** up, you'll have some peanut butter jelly up in your a$$hole" and I was like started laughing and everyone started laughing so hard! That one girl just laughing and fell on floor, laughing even harder!!! Ah, good day lol

The most funniest day for me - and the entire class too, I'll bet you that, - was when my English 9 teacher started to b*tch at me and I got so annoyed, and I simply packed up my backpack and stood up, in front of the entire class, and walked out right in front of the teacher while she was lecturing. 
A guy named Dom said something similar to this line- "Oooh, burn." and the entire class rofled out loud. Someone else said this 45 minutes later - *cough* "pwnd." *cough* (he literally coughed and spoke pwnd clearly and coughed.
Once again, laughing madness ensued. 

(BTW: My best friend who was in the class at the time, who could HEAR what happened, told me what happened, that's how I know while being deaf. =P)

Snowdeath : Lol that's pretty funny well i don't go 2 school so no funny day's

The following story is 100% true. my friend put his hand up for help in like year 8 or 9 so aggggges ago the teacher took a while and he didnt know whether she was coming or not and so he kept turnign round as you would. he then turned round again after a while but didnt realise that she was leaning over him. this teacher had massive boobies and poor charlie was basically suffocated by them, he turned his head straight into them.
while a normal person would of awkwardly turned away he was simply so caught off guard he accidently like motorboated her because he didnt know what was going on. it made our class laugh for soooo long :p (if you dont know what motorboat means then look it up on google its to hard to explain lol) anyway that was the funniest thing ever hehehe

My funniest day had to be when me and my freinds were reading a calvin and hobbes book. 

Me:Quit turning the page I'm not done reading it yet!
PA: Students, please wear a coat outside because it's a bit cold outside.
Me: A bit?It's like 30 degrees outside!
Sophia (she's from Hong Kong): 30 degrees? That's hot!
Mike : No Sophia, Fahrenheit.
Sophia: Oohhhh

My funniest day at school is when a few of us gathered a ton of whopee cushions and put them on everyone's seat and it was so funny when everyone sat down when class started!

The funniest day in schol was when the teacher left the class and the Micheal Daly a student gathered some people to play indoor cricket That was my funniest school day.

Hmmm. I have a lot of those. This is the first one I thought of though:

Once during our senior year, me and my friends were all sitting in our usual spot and one of my friends said something kinda weird (I forget what). This prompted my friend Patrick to pick up the paper sack he had and hit the guy with it. Patrick had apparently forgotten that he still a container of ranch still in the sack. The paper sack EXPLODED and ranch dressing sprayed all over me, my friend Tiffany, and the guy she was sitting next to. 

Patrick, me, my friend Katie, and the guy Tiffany was sitting next to, all collapsed on the ground from laughing so hard. Meanwhile, Tiffany was just all, "Now I'm going to smell like ranch all day!" and stormed off. It wasn't very nice, but that only made us all laugh harder. xD A bunch of people at surrounding tables, who had seen what happened, just looked at us like, " WTF" and a teacher came over and asked what happened, but none of us could say because we couldn't stop laughing. 

Nowadays, Tiffany can laugh about it, too, but wow, she was MAD. =P

Well, this happened last semester in Anatomy and Physiology Lab. We were onto the urinary system, and we were each given a paper for what we had to drink and how much the morning of our next lab day. For the lab, everyone had to pee in a cup and do tests on their own urine. Not one by one, because that would have been so awkward. All the guys went to the men's room, and the women to the women's room. I decided to break the awkward silence in the room when we were handed our cups by asking if they could provide me with a magazine. The professor was speechless to say the least.
