Akpos On Egyptian Excursion

The students of Warri Grammar School went on excursion to Egypt. On the tomb of Pharaoh was written “1102BC”.

The teacher now asked “who knows what this means?”
Nobody except Akpos raised his hand but the teacher was not comfortable and pretended not to take notice of him.
She then asked again and yet only Akpos hand was still up.

So she allowed him to answer. Akpos said “Na Pharaoh BB Pin be that”
