The funny part of Chinua Achebe: A rat swallowed a diamond. The owner of the diamond contacted a man to kill it. 

When the rat hunter arrived, there were more than 1000 rats bunched up and one sitting by itself away from the rest.  He spotted and killed the one sitting by itself and to the owners surprise, it was the one that had swallowed the diamond. 

The amazed owner of the diamond asked, "How did you know it was that rat?" He responded very easy, When idiots get rich, they don't mix with others!! 😂😂😂 Get the lesson
