[مجد محمد]

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 attack 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.
