A college professor was in a confessional booth talking to the priest.
"Father, my wife has been out of town," he said. "After class today, a beautiful young co-ed invited me back to her dorm room. I've never been in a situation like this before. I can't believe it myself, but I agreed to go. We started having sex and ... um ... her roommate walked in. Next thing I know, she joins us and all three of us are having sex."
The priest sighs deeply.
"The violation of marriage vows is a serious sin," the priest said. "I'm not sure that I can give you any penance right now that would fit such a grave sin."
"Um ... I'm sorry," the professor said. "I'm not Catholic."
"Then why are you telling me this?" the priest asked.
"Are you kidding?" he said. "I'm telling everyone!"
