Then she reverses direction, calling the ring finger 6, middle finger 7, the first finger 8, and her thumb 9, after which she calls her first finger 10, and so on. If she continues to count in this manner, on which finger will she stop? Calculate the number 100

An Almost Affair
A married man goes into a confessional and says to his priest
"I had an affair with a woman... almost."
The priest says, "What do you mean, almost?"
The man says, "Well, we got undressed and rubbed together, but then I stopped."
The priest says, "Rubbing together is the same as putting it in. You're not to see that woman again. For your penance, say 5 Hail Marys and put $50 in the poor box."
The man leaves the confessional, says his prayers, then walks over to the poor box.
He pauses for a moment and then starts to leave.
The priest, who was watching, quickly runs over to him saying, "I saw that, you didn't put any money in the poor box!"
The man replies, "Yeah, but I rubbed the $50 on the box, and apparently that's the same as putting it in."
