Which sport do you suddenly become an armchair expert in for just two weeks a year?

For a fortnight everyone knows exactly what a let is. Then it's all forgotten until next June.

Once every four years the whole country falls head over heels for a big stone and two brooms. Nobody knows the rules, everybody has a view.

You know nothing about horses, but you've got a fiver on the one that sounds like your nan. And you're shouting louder than anyone.

You didn't go to either of them. You'll still cheer one on like your life depends on it.

Suddenly you're an expert on safety shots and why he really should have gone for the red. Pass the biscuits, quietly.
