Which one is Awang? Hmm~~

Well..as far as i know...there can only be one Awang,
But there are so many people in the hall...
For normal people, it would be impossible to guess the real Awang among these people
Thank God i ain't normal
Although i did took a while to spot out two people from the crowd

Problem Statement: How to find the real Awang?
Hypothesis: Look for the one who did the most talking.
Manipulative variable: Man who talks( Grey coat/black coat)
Responding variable: The real Awang
Constant variable: Awang is a man (gua)

Ok..let's skip the procedure part..(coz i always had problem writing those in high school >.<)
"FINDING AWANG"
I asked an innocent boy, who is the real Awang?
He said, I'm pretty sure it was the black coat one.
I asked why.
He said, it must be him!
I said, ok lor~

And then comes the climax...
A brave heroic girl stands above the others
She reached the mike, and asked Awang (Grey coat/black coat)
**I skipped the question that girl asked**--->it's really not that important here
I looked up..
the black coat speaks first...
The innocent boy looked happy
But then, the grey coat said something...(i can't remember, sorry)
The boy looked down

RESULT:
Awang is the "grey coat man". But wait, the story has not ended yet!

Now, here comes a new question...
IF THE GREY COAT IS AWANG, THEN WHO IS THE BLACK COAT?
