My school had this really anal and belligerent maths teacher. He had a rule that you had to line up on the left side of his door before class, and he'd stand there and make notes on who was in a rush and who was talking etc. If you got three black marks in one week, you got sent to the headmaster.

In other words, he was a real prick.

One day he wasn't there waiting for us, so we huddled in groups talking. Suddenly he jumped out the classroom and started screaming at us to line up against the wall and shut up. I was at the front of the line, so had a perfect view of his purple face and the pulse in his neck throbbing fit to burst. Then he got even more worked up and started shrieking at 'that girl in the skirt' to get in line or she'd be in detention for the rest of term. She ignored him, so he marched down the line, and grabbed her, and started yelling.

Only... it wasn't a girl: it was the head of the Language department, who'd stopped off to talk to her son, at the end of the line.

We all got in trouble for lauging at him, but the last laugh was on us when he didn't get his contract renewed.

Oh, happy days.
