Jokes about smart people

From this book "Who Took the Happiness of Children", it tells a joke: a murderer was thrown into 18 hell after his death, and when he was sad, he suddenly heard someone sigh at his feet. I was very surprised and asked, who's down there? The following person replied: I am a teacher, on the 0/9 floor of Hell/Kloc. The murderer was even more surprised: isn't hell only 18 floors? Why is there a 19 floor? It says: This is specially designed by the Prince of Yan. The murderer said: murder is the worst crime. Is your crime more serious than murder? The man said, you don't know. People have two lives, one is life and the other is wisdom. Killing life only hurts the body, killing wisdom destroys the soul. He was sent down to 19 floor for killing many children by mistake.
