Duck or get stabbed
A fantastic game played at Ashfield High School in New South Wales (Australia).
Get everyone's pencil sharpeners, and remove the blades. You may need a screwdriver.
Then, turn the ceiling fans up to full, and when the time seems right, yell "duck or get stabbed", and throw the blades into the fan.
Children and teacher alike would then dive under their desks to avoid receiving a chaotic facial slash.
This being Australia, the teacher probably didn't cry and leave the teaching profession forever. She probably said "heh, nice one, blue" before hopping onto a jetski and doing a double-dunny in Gedunga Bay, or something like that.
