The Three Nuns There were 3 nuns on a train and they had been talking for some time when they decided to pass the time by telling each other what their greatest sins were. 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 take 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's 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".
