Whoosh - splat!
I remember a teacher at school who was a committed cricket fan - and player. He was a demon bowler, and used his mad skillz in the classroom: talking, not paying attention or dozing off were likely to be met by a heavy wooden board rubber whistling past at hypersonic velocity, missing your head by a heart-stoppingly low number of angstroms, then crashing deafeningly against the back wall. The wall was covered with chalk-splats, giving testimony to the number of intercontinental ballistic board-rubbers that were launched, but I never once saw him misjudge it and actually make contact with a trangressor's cranium.

We had a chemistry teacher like that, but he wasn't such a good shot as I received a bruise on the back of my neck and chalky blazer!!

Are you sure he wasn't just boss-eyed and aiming for your heads?

Boss-eyed?
Couldn't control his pupils?

My old head of sixth from claimed he had a teacher like this
Except he swore that he had actually seen the guy curve a board rubber around another pupil's head in order to clip the naughty child on the ear.

Classy

...but probably mythical.

It's difficult to see how you could put "spin" on anything as non-spherical as a board rubber in any predictable way.

You just can't do this with a Smart Board.
