We had an ICT teacher a little like this back at our old school. Except he was a drunk who got pissed off at the slightest thing, and once grabbed a chair with a kid still on it, lifted it over his head and threatened to knock another kid out with it.
Then he transferred to my cousin's school, and oh hilarity, the moment he got there, their grades fell through the floor into the rat-infested basement.
