Two primary school boys were arguing about a plane flying overhead.

Kwame: President Kufuor is on that plane
Kojo: No, he's not
Kwame: I am sure he is
Kojo: No way, he just arrived in Accra yesterday

As the argument was going on, their class teacher Kofi walked by and the two boys decided to ask him.

Kwame: Teacher Kofi, don’t you think this plane that is going in the sky is President Kufuor?
Teacher Kofi: Hmmmmm... I don’t think this is the President
Kojo: You see, I told you
Kwame: ...but why do you say it's not him?
Teacher Kofi: Because if this is really President Kufuor you will see 3 police motorcycles in front of the plane and two at the back.
Kojo: Teacher Kofi, you are so 'wisdom'
