Roger, who was 19 years old, was buying an expensive bracelet, to surprise his girlfriend on Valentine's Day, at a very smart jeweller's shop in Hatton Garden, London. The jeweller inquired, "Would you like your girlfriend's name engraved on it?" Roger thought for a moment, grinned, then answered, "No, instead engrave 'To my one and only love'." The jeweller smiled and said, "Yes, sir; how very romantic of you." Roger retorted with a glint in his eye, "Not exactly romantic, but very practical. This way, if we break up, I can use it again."

A rabbi and a priest crash into each other at a four-way junction. They both get out of their cars and look at the wreck. They both thank God they are OK, and the priest says, ‘This must be a sign that God wanted us to meet.’ The rabbi says, ‘Yes, indeed, let’s drink.’ So the rabbi gets out some wine. They toast each other and the priest drinks his glass. But the rabbi doesn’t take a taste of his drink. Priest: ‘Why aren’t you drinking?’ Rabbi: ‘I’m waiting for the police.’
