The only year I did well in Maths at school was when I had an ex-alcoholic teacher, using an amazing ability to engage us schoolboys.
How did I know he was alcoholic?
He told us: regaling us barely post-pubetic boys with extraordinary stories about his lecherous drunken adventures. He was amazing - half his class consisted of these outrageous stories (with a secret sub-plot I now realise), the other half, complex maths reduced for clearly for eager, listening minds.
We all looked forward to Maths that year.
