A lawyer sold his well to a teacher. Two days later, the lawyer came to the teacher and said, “Sir, I sold you the well, but it’s not with the water inside! If you want to use the water, you will have to pay extra.”

The teacher smiled and replied, “Yes, I was about to come to you. I was going to say that you should take your water from my well, or else you will have to start paying rent from tomorrow.”

Hearing this, the lawyer got nervous and said, “Oh, I was just joking!”

The teacher laughed and said, “This is how people like you become lawyers after studying with us.”
