"I must admit," responded the Rabbi, "I was always very very curious about how pork tastes. So once, just once, I stopped at a barbecue restaurant when I was on a vacation and ate a pork sandwich. In fact, it was so delicious, I ate four of them - knowing, of course, I'd never have the nerve to sin again like that."
The Catholic joined in, "Well, I had the same curiosity about sex, and that being forbidden, I didn't know which sex would appeal to me more. So once, while in seminary, I had a sixteen-year-old girl and her brother at the same time. I was so overcome with feelings of guilt that I've never done anything like that again. Well, what about you, Pastor Bob?"
The Methodist said, "My besetting sin is gossip, and I just can't wait to get back and tell everybody in town what you guys have said!"
