Nasrudin walked into a shop one day, and the owner came forward to serve him.
Nasrudin said, "First things first. Did you see me walk into your shop?"
"Have you ever seen me before?"
"Then how do you know it was me?"
Nasrudin sat on a river bank when someone shouted to him from the other bank:
"Hey! how do I get across?"
"You are across!" Nasrudin shouted back.
"Why are you sitting at the crossroad Mullah?"
"One day something will happen here, and a crowd will gather. When that comes about, I may not be able to get close enough to see - so I am preparing my position now."
