One of the funny stories I recall took place in my last period class in 8th grade. My highly despised teacher was lecturing us all one day and was in a grumpy mood. She was going on and on about maturity or something along those lines. There was a chair in the middle of the room and as she went to sit down in it, something snapped in the chair and the loud noise made me look up from the book I had on my desk and I saw her falling back in the chair. She moaned as she reached out to her desk and was so close to completely falling back. But just her breaking the chair and almost falling made everyone laugh for about 10 minutes straight. People laughed for so long she eventually had to say "It really wasn't that funny, stop laughing" which made everyone laugh harder.
