An elderly man was taking one of those long, interminable train journeys across central Russia early in the twentieth century – the train stopped at a dusty one-street town in the arsehole of nowhere and the conductor announced there would be a five-hour delay.
The man walked the single street several times until he had seen everything there was to see, when he spotted a little shop with watches hanging in the window, so he decided to go in and get his own watch cleaned.
He went in to find a wizened old man sitting behind the counter; "could you clean my watch sir?" he asked
"I don't do watches", said the old man, "I'm a mohel"
"Then why do you have watches hanging up in your window?" asked the man.
"What should I have hanging up in the window?" came the response.
