An igbo man opened a zoo and tagged the entrance fee at #5000.But no one came to the zoo.He reduced the price to #3000 and still no one came.He reduced the price again to #2000,#1000 and later #500 and still nobody came to the zoo. He then made the entrance fee free and announced it.The next day,the zoo was filled with people of different kind from different places.The igbo man now thought about how to earn back all the money he used in the opening of the zoo,then he now decided to do something tricky.He locked the zoo gate and released a lion.Everybody began to run up and down then he now tagged the exit fee at #6000 and everybody was paying the fee just to save thier lifes.
