A Prof and Akpors was seating next to each other in a long flight.
Prof said to Akpors lets play a game, I will ask you a question and if you didn't get the answer, you will pay me $50, and if u ask me a question and I didn't get the answer, I will pay you $5000.
The Prof started : What is the distance from the earth to the moon ? Akpors doesn't say a word, he reaches his pocket and pulled out a $50 and gave him. Now it's akpors turn to ask.
He said : what goes up in the hill with 3 legs and comes down with 5 legs ?
The Prof thought for a long time, searches the net, and asked all his smart friends but couldn't get the answer.
He reaches his pocket and pulled out a $5000 and gave it akpors.
Prof got mad and asked Akpors : well, what the hell goes up the hill with 3legs and comes down with 5 legs ?.
Akpors just deep his hand into his pocket and gave Prof $50 and said : I also don't know.
