Joke- Akpos never learn

Akpos enters a barber shop. The barber
whispers to his customer:
BARBER: This is the dumbest boy in the world.
Watch while I prove it to you.
The barber puts a N50 note in one hand and
two N10 notes in the other,then calls the boy
and asks:
BARBER: Which do you want, boy?
Akpos takes the two N10 notes and leaves.
BARBER: What did I tell you? Akpos never
learns!
Minutes later, when the customer left, he sees
Akpos coming out of the ice cream store.
CUSTOMER: Akpos, May I ask you a question?
Why did you take the N10 notes instead of
the N50 note
Akpos replied, "Because the day I take the fifty
naira note, the game is over!"
It's better I collect N20 everyday.
