My favourite Jewish joke
A elderly man was journeying across the Russian Steppes on a long train Journey
The train stopped at a small, dusty one-street village and the announcer informed the passengers that they would be there for several hours to take in fuel and water
The man stepped down and walked up and down the only street, within five minutes he'd seen all there was to see; he looked at his pocket watch and decided to see if there was anywhere among the handful of tiny buildings where he could get it cleaned
At the end of the town he found a dusty looking shop with watches hanging in the window so he stepped inside, took out the watch and handed it to the stooped old man behind the counter asking him could he clean it
"I'm afraid I can't" said the man, I don't do that sort of thing, I'm a 'mohel' (a priest who carries out circumcisions)
"But you have watches hanging in your window" the man said, somewhat puzzled
"What should I have hanging in my window?"
