An Irish priest and a Rabbi found themselves sharing a compartment on a train.  After a while, the priest opened a conversation by saying, "I know that, in your religion, you're not supposed to eat pork... Have you actually ever tasted it?"

The Rabbi said, "I must tell the truth.  Yes, I have, on the odd occasion."

Then the Rabbi had his turn of interrogation.  He asked, "Your position also comes with some forbidden activities.  I know you're supposed to be celebate, but..."

The priest replied, "Yes, I know what you're going to ask.  I must admit that I too have succumbed to temptation, once or twice."

There was silence for a while.  Then the Rabbi peeked around the newspaper he was reading and said, "Better than pork, isn't it?!"
