There are 2 nuns who went out the convent for selling cookies. One of them is known as Sister Mathematical (S.M.), the other is known as Sister Logical (S.L.). It is getting dark and they are still far away from the convent.
S.L. : Have you noticed a man that has been following us for the past half hour ?
S.M. : Yes, I wonder what he wants.
S.L. : It’s logical. It’s logical. He wants to rape us.
S.M. : Oh, no ! At this pace he will reach us in 15 minutes at the most. What can we do ?
S.L. : The only logical thing to do of course. We have to start walking faster.
S.M. : It is not working.
S.L. : Of course it is not working. The man did the only logical thing to do. He also started to walk faster.
S.M. : So, what shall we do ? At this pace, he will reach us in less than 1 minute.
S.L. : The only logical thing we can do is to split. You go that way and I will go this way. He cannot follow both of us.
So, the man decided to go after Sister Logical.
Sister Mathematical arrives at the convent and is worried because Sister Loigical has not arrived yet.
Finally, Sister Logical arrives.
S.M. : Sister Logical ! Thank God you are here. Tell me what happened?
S.L. : The only logical thing happened. The man could not follow both of us, so he decided to go after me.
S.M. : So, what happened. Please tell me.
S.L. : The only logical thing to happen. I started to run as fast as I could.
S.M. : So what happened ?
S.L. : The only logical thing to happen. The man also started to run as fast as he could.
S.M. : And what else ?
S.L. : The only logical thing to happen. He reached me.
S.M. : Oh, no. What did you do then ?
S.L. : The only logical thing to do. I took my dress up.
S.M. : Oh, Sister. What did the man do ?
S.L. : The only logical thing to do. He put down his pants.
S.M. : Oh, no ! What happened then ?
S.L. : Isn’t it logical Sister ? A nun with her dress up runs faster than a man with his pants down.
