There were two nuns...
One of them was known as Sister Mathematical
(SM),
and the other one was known as Sister Logical (SL).

>> It is getting dark and they are still far away from the
>>convent.

>> SM: Have you noticed that a man has been following us for
>> the past thirty-eight and a half minutes? I wonder what he
>>wants.
>>
>> SL: It's logical. He wants to molest us.
>>
>> SM: Oh, no! At this rate he will reach us in 15 minutes
>> at the most! What can we do?
>>
>> SL: The only logical thing to do of course is to walk faster.
>>
>> SM: It's not
working.
>>
>> SL: Of course it's not working. The man did the only
>> logical thing. He started to walk faster, too.
>>
>> SM: So, what shall we do? At this rate he will reach us in one
>>minute.
>>
>> SL: The only logical thing we can do is split. You go that way
>>and
>> I'll go this way. He cannot follow us both.
>>
>> So the man decided to follow Sister Logical.
>>
>> Sister Mathematical arrives at the convent and is
>> worried about what has happened to Sister Logical.
>>
>> Then Sister Logical
arrives
>>
>> SM: Sister Logical! Thank God you are here!
>> Tell me what happened!
>>
>> SL: The only logical thing happened.
>> The man couldn't follow us both, so he followed me
>>
>> SM: Yes, yes! But what happened then?
>>
>> SL: The only logical thing happened. I started to run
>> as fast as I could and he started to run as fast as he could.
>>
>> SM: And?
>>
>> SL: The only logical thing happened. He reached me
>>
>> SM: Oh, dear! What did you do?
>>
>>
SL: The only logical thing to do. I lifted my dress up.
>>
>> SM: Oh, Sister! What did the man do?
>>
>> SL: The only logical thing to do. He pulled down his pants.
>>
>> SM: Oh, no! What happened then?
>>
>> SL: Isn't it logical, Sister? ........
>> A nun with her dress up can run faster than man with his pants down.
