Conkers "one-oh-one"

As Zebedee had his first day at senior school today I obtained some horse chestnuts, dismembered a pair of trainers and forced them to learn the fine old schoolboy game of conkers. After about an hour of fruitless hacking at each other they grumped off telling me it was rubbish.
When I was a lad it was the only thing I looked forward to on the return to school after the summer holidays.

Oh well, next week, MARBLES!
