A local man was proclaiming that no one could trick him. Nasrudin heard this, and said to him one day, “Just wait here for a while, and I’ll figure out how to trick you.”
The man waited and waited and waited. A merchant from across the street noticed him, and asked, “What are you waiting here for?”
The man replied, “I’ve been waiting here for an hour, just to see if Nasrudin can trick me. He still hasn’t come back yet.”
“Well then,” the merchant said, “it appears that you needn’t wait here any longer, for you’ve already been tricked.”
