There was a guy I knew who was a visitor to Butlins where I had got into it from going to it in air and I asked for a job and got it and I diverge as there is a spell here as I met a guy who had 3 fingers on one hand which he said he had been born with but later said he it got caught in  machinery in the school woodwork but we thought he was trying to create sympathy from females. I've never heard of that before as I've never met anyone with extra digits on the hand which is called 'polydactylies'.
