There's this old priest who got sick of all the people in his parish who kept confessing to adultery. One Sunday, in the pulpit, he said, "if I hear one more person confess to adultery, I'll quit!"

Well, everyone liked him, so they came up with a code word. Someone who had committed adultery would say they had "fallen". This seemed to satisfy the old priest and things went well, until the priest died at a ripe old age.
