Playing Pool
Quite a few years ago I was at the pub- had a couple of drinks nothing unusual- my partner and I decided to play a game of pool. We often did this as many do. This time however every shot I took would go in the hole. We were asked to have a game with another couple and again my shots would go straight to the pocket. I was asked by onlookers if I was a professional - it was puzzling.
It never happened again. Why did this happen?
