He should just post in here, the inimitable billytea in Natter:
My school did have some odd teachers.
There was another science teacher who had trained as a racing car driver. HS owned some property on the coast that it used for retreats, campouts, excursions and such like. Anyway, to get there you traversed a winding mountain road. So this teacher used to drive a bus-full of students down there on occasion. If he was feeling bored, halfway down he'd start stamping on the clutch and screaming "No brakes! No brakes!!!"
This is the same guy that demonstrated the difference between potential and kinetic energy by smashing test tubes on the floor. He once relief taught my science class (I never had him as a regular). We spent the entire class just reading the coursework set by the regular teacher, while he amused himself by setting fire to the desk.
Of course, there was a class in Religious Studies, where another teacher gave this impassioned little speech which ended with the rousing plea, "Just say no to peer pressure!" So it started with one or two people up the back, then gradually spread through the entire class, until everyone was thumping their desktops in unison and chanting "No! No! No!"
Heh. You'd think I'd have more highlights to show for six years of my life, wouldn't you?
