I may need to go and be alone in a dark room for a while....
But it does remind me of a joke by the great Scottish comedian Chic Murray:
I was walking through the Olympic village the other day and I saw a man with a big stick. I said 'Are you a pole vaulter?' he sad 'No, I'm German. How did you know my name was Walter?'
Comic genius.... Another gem:
So I got to my bed and breakfast. The landlady opened the door in her dressing gown. I thought 'Funny place for a door'. She said 'Have you a good memory for faces' I said 'Yes, why?' she said 'There's no mirror in the bathroom'
