'The Lubavitch challenged Oxford University to a rowing contest but discovered that Oxford were twice as fast as they were. So the Lubavitch cox sent a spy across to Oxford to find out why and how. A few hours later the spy returns. “Nuh,” says the Lubavitch cox, “tell all.”
“Well.” says the spy, “they do everything the other way round to us.”“Explain,” says the cox.
“It's simple,” says the spy, “they've got eight men rowing and one man shouting!'
This is the standard of the humour there....run as far away and as fast as you can. ;-)
