At a local circus under the bridge in lagos, a guy was entertaining a crowd with his monkey, then he asks that anyone who makes the monkey laugh recieves a price. if u can make it cry, another price awaits you and if you can make it run into its cage, u have a better price waiting.

So different guys came to try there luck but no body suceeded. Then came this akwa-ibom guy. He walked up to the monkey, whispered to it and the monkey began to laugh. He was higly applauded and got his prize. then the entertainer called for the people to make the monkey cry. all tried but the monkey didn't budge so this guy came again, whispered to the monkey and the monkey began to cry.
At this point i began to suspect the guy was using juju(voodoo) but i kept watching. Then the entertainer called for the last one. Once again, everyone that tried failed and once again this guy came out, whispered to the monkey and the monkey not only ran into its cage but shut the door, and the guy got his price.
I swore never to leave that guy till i get the secret, so i confronted him and asked if u used juju but he denied. Then i asked him what he told the monkey that made him laugh. The guy said (in his accent)"well i just tell am where i dey work" i asked where he worked and he said Nigerian Railway Co-operation
Ok what did u tell him that made him cry? "well i just tell am how much them they pay us so im start to cry" . Then what did u tell him to make him run into the cage? "well i no tell am much" he said, laughing. "please tell me"  and he replied, "well i just tell am say we get vacancy for the place , weather im go like to come work?"
