A priest and a rabbi found themselves sharing a compartment on a train.

After a while, the priest put down his book and opened a conversation by saying, "I know that in your religion, you're not supposed to eat pork... but have you really never even tasted it?"

The rabbi closed his newspaper and responded, "I must tell you the truth. Yes, I have, on the odd occasion."

The rabbi had his turn of interrogation: "I know that in your religion, you're supposed to be celibate, but..."

The priest interjected, "Yes, I know what you are going to ask, and yes, I have succumbed to temptation once or twice."

The two resumed their reading. It was silent for a while.

Then the rabbi peeked around his newspaper with a smile and said, "Better than pork, isn't it?"
