The same priest was seated next to the same rabbi at the ecumenical dinner later that week. When the hors d'ouvres came around, the rabbi declined the bacon-wrapped scallops.

"Come on," said the priest. "This is great, try it."
"No. we Jews do not eat pork."
"Not even a bit of bacon?"
"No."
"Never? Come on, I swear your secret will stay with me."
"OK," admits the rabbi. "I tried bacon once when I was a young man. But what about you Catholics? You don't marry, but surely you have had sex at some time?"
"Never," said the priest.
"Come on ... your secret is safe with me," said the rabbi.
"Well," said the priest. "Yes, ... when I was a teenager I had a girlfriend before I went to the seminary and we made love once."
"Better than pork, isn't it?"
