Whats the Fastest thing in the World?

A Company wanted to employ for a Senior officer post in Abuja and after interviewing about 1000 candidates, 2 candi9dates came tops and the Company still only needed to take just one person. The three guys are Usman (Hausa), Segun(Yoruba) and Chibike (  Ibo)

So one of the Manager decided to test them with one last Question.

HR Manager: What is the Fastest thing in the world, you Segun
Segun: Hmm, Sir the fastest thing in the world is the speed of light, It has been comfirmed and all theory attest to that.

HR Manager: Hmm, Ok. what about you, Usman
Usman: Hmm, Segun i sright, however the "blibk of an eye" is equally that fast because no one ever knows when they blink

HR Manager: That's an Interesting thot, What about you Chibike?
Chibike: Ah, this is tough as both the speed of light and a eye blink are equally fast. However, there is nothing as fast as a "watery shit", like when you have diarrhea

HR Manager: Chibike, What on earth do you mean?
Chibike: Sir, Let me explain, A Fortnight ago, i was at a friends place and i went to eat beans with salad and my stomach started purging, Sir, I decided to rush home, when i got home, Before i could put on the light or blink my eye, "I don shit for body" 

Dont ask me who got the Job - You decide....hahahaha
