Two nuns leave their convent to sell biscuits.
One of them is known as Sister Math (SM) and one as Sister Logic (SL).
It is getting dark and they are still far away from their convent …
SL: “Did you notice that a man has followed us in the last half hour?”
SM: “Yeah, I wonder what he wants.”
SL: “That’s logical, he wants to rape us.”
SM: “Oh no, at the moment he will have reached us in 15 minutes at the latest What can we do?”
SL: “The only logical reaction for us is to run faster.”
Both nuns speed up their steps.
SM: “It does not help.”
SL: “Of course it does not help – the man did the most obvious thing he could do – he also started to run faster.”
SM: “Well, what can we do, he’ll reach us in a minute at the moment.”
SL: “The only logical reaction for us is to split us up, you go down there and I walk along here, he can not follow both of us.”
The man decides to follow sister logic.
Sister math reaches the convention and is very worried because Sister Logic has not arrived yet.
Finally, Sister Logic also arrives.
SM: “Sister Logic, thank God you are here! Tell us what happened.”
SL: “The only logical thing that could happen, the man could not follow us both, so he decided to follow me.”
SM: “And what happened, please tell us.”
SL: “The only logical thing happened, I started to run as fast as I could.”
SM: “And then?”
SL: “The only logical thing that could happen is that the man also started running as fast as he could.”
SM: “And on?”
SL: “The only logical thing happened, he caught up with me.”
SM: “Oh no, what did you do then?”
SL: “The only logical thing that could happen, I raised my robe.”
SM: “Oh, sister, what did the man do?”
SL: “The only logical thing happened, he pulled down his pants.”
SM: “Oh no, and what happened then?”
SL: “Is not that logical, sister, a nun who has lifted her robe can run faster than a man who has pulled down his pants …”
