Once upon a time, in a place called Persia, there was a really smart man named Nasiruddin Hojja. He was very knowledgeable and clever. One day, as he was traveling towards the capital, something tricky happened. A person came up to him with a letter and asked, "Can you please read this letter for me?" Hojja was in a hurry and didn't really want to spend time reading the letter for this person. So, he came up with an idea. He said, "How is that possible?" which surprised the person. Then Hojja explained, "You see, you're wearing a big turban on your head. Usually, only smart people wear turbans." The person was a bit confused and said, "Okay, but what does that have to do with anything?" Hojja quickly took off his own turban and put it on the person's head. He said, "Now you're wearing the turban, so you should be able to read the letter yourself." After saying this, Hojja walked away. The person felt embarrassed and didn't know what to do next.
