Holy Shergar!

Earlier, at my mother's getting my stuff together after accidentally staying overnight (sounds better than saying I fell asleep in the chair and woke up at 4a.m.), she had the TV on while they were getting ready for the Grand National. (She wasn't watching it, in fact she was asleep, I think, which is pretty common these days). There was a list of all the runners; my eye ran down the list and when I read Bellabriggs (actually, I think it's Ballabriggs, but I misread it at the time) I thought, That'll be the winner, then. I left before the race started.

Why do I never get thoughts like that when I am near a betting shop or otherwise able to do something about it?
