One day, a Catholic priest and a Rabbi were in the same compartment on a train. A short time into the journey, the priest lost interest in the book he was reading and decided to start a conversation with the Rabbi. "In your religion," He says. "It is written that you must never eat pork. But how do you know if you like it or not if you've never even tried it before?"
At that moment the Rabbi put down his magazine and replied "My friend. If I am totally honest with you, I must admit the truth. I have indeed tried pork from time to time."
"And you?" questioned the Rabbi. "In your religion, it is written that you must never stray from the path of celibacy. But how do you."
The priest stopped him there. "I know what you are going to ask and yes, if I am totally honest with you, I must admit the truth. I too have indeed given in to the temptation of carnal desires once or twice."
They both smiled and went back to reading. A few more stations flashed by and after a while, the Rabbi broke the silence, peeping over the top of his magazine with a big grin and said "It's better than pork, isn't it?"
