There where 3 nuns on a train and they had been talking for some time when they decided to pass the time they decided to tell each other what their greatest sins where. The first nun got up and said, "My greatest sin is sex. Every year I go out for a week and become a prostitute. Of course I put all the money I earn in the poor box but that is my greatest sin." The second nun got up and said, "My greatest sin is drinking. Every year I the money out of the poor box and drink for one consecutive week." The third nun was sitting there being very quite. The other nuns say "come now we told you our worst sins, what is yours." The third nun got up and said, "My greatest sin is that I am a gossip and I can't wait to get off this train."
