A man goes to confession

He says to the priest: "Forgive me father for I have committed adultery... I think."

"What do you mean you think? You're not sure if you've committed adultery?" Inquired the priest.

"Well father. I was with a woman and things were about to get nasty. I THOUGHT about putting it in but never actually put it in. And so I decided to leave."

"Of course that's adultery!" Replied the priest. "THINKING about putting it in is the SAME as putting it in. Now for penance I want you to pray 10 Our Fathers and leave $50 in the donation box."

So the man leaves the confessional and says his prayers. Then he approaches the donation box for a moment and begins to leave, but the priest runs over and stops him.

"My son! I saw that you prayed your penance but you haven't made your donation!"

The man replied, "Well Father, I thought real hard about putting it in!"
