A married Irishman went into the confessional and said to his priest, "I
almost had an affair with another woman."
The priest said, "What do you mean, almost?"
The Irishman said, "Well, we got undressed and rubbed together, but
then I stopped."
The priest said, "Rubbing together is the same as putting it in. You're
not to see that woman again. For your penance, say five Hail Mary's and
put $50 in the poor box."
The Irishman left the confessional, said his prayers, and then walked
over to the poor box. He paused for a moment and then started to leave.
The priest, who was watching, quickly ran over to him saying, "I saw
that. You didn't put any money in the poor box!"
The Irishman replied, "Yeah, but I rubbed the $50 on the box, and
according to you, that's the same as putting it in."
