The Phenomenon.

In the late 1980s, there was a mad man in Onitsha, Nigeria. He was not just mad but known to have been in the sad state of insanity for decades.

One day, a luxurious commercial bus was about being boarded by a long line of passengers who were heading to Lagos City. At that moment, the mad man came along. As he did, a couple of armed police officers whose job was to escort the bus on its journey, ordered the mad man to leave the area.

"Hey!" the mad man yelled at the passengers on the line. "If I were you, I would not board this bus."

"Alright, thanks for telling them." the police officers yelled back at the mad man. "Now, you can leave."

"I'm warning you people..."  the mad man yelled again, ignoring the cops. "Do not board this bus...there is danger ahead..."

At this moment, one woman turned to the mad man to ask. "What danger are you talking about?"

Typically of the insane, the mad man laughed hysterically in reaction to this question.

"Because..." he continued to laugh. "Among you passengers are some notorious armed robbers who intend to rob you along the way."

Initially, no one took the mad man seriously. But as he kept on saying the same thing over and over, some of the passengers finally began to feel wary about boarding the bus. In a bid not to lose passengers however, the bus driver pleaded with the police officers to do something. 

And so, at gun point, the officers decided to conduct a body search of all male passengers. It was soon discovered that six men had pistols tucked under their shirts and they confessed that they had intended to rob all the passengers whenever the bus took off. This was a phenomenon that baffled everyone at the bus station.
