But a Maths teacher being naked? They always seem the type to be boring and totally not willing to let themselves go.

exactly, it's the traditional buttoned up types you have to watch out for. After so many years of uber-conservative behavior, they tend to snap, sometimes spectacularly.

Just remembered another odd moment. Back in Junior high when my severely obese social studies teacher showed up dressed as cupid. Skin tight red leotard, a diaper, wings and a sparkly red bow with sparkly red arrows. took a LOT of alcohol to kill off THOSE memory cells.

apple wars!!!! all the years: 8,9,10,11,12 at resses just ditch apples at each other... my friend got hit and had to wear a sling haha

With that in mind, snowball fights with the entire school are fun.

YES. Like that time we got snowed in at college.. They closed it at 1 in the afternoon, but no one could leave, so there was a continuous snowball fight from then until half 9. Crazy.

And, we made a killer snowman . Untill this random kid came along and kung-fu'd him to pieces :(

It doesn't snow in ATL. Which equals no snowball fights :'(

You could always scrape the frost from inside your freezer then drop it down someone's pants when they aren't looking then run away very quickly. That's what I'd do anyway.

OHHH
The day we found out our old history teacher used to be a cage dancer.
'Red Hot Reggie'
Bwhahahaha!

Well that could be a possibility.

I also remember this one time that my school was actually situated on top of a dimensional boundary place that let hell into it, and me and my friends battled demons while dealing with average teenage troubles.

(I use television as a substituion for my lack of cool memories)
