A professor drove into a petrol station in his sleek state of the art range rover sports.

Professor: guy, abeg, give me full tank.

Fuel Attendant: Sir, I don't speak pidgin, I only speak English

Professor: Ok! good morning, I currently feel a profound desire to replenish the propelling of my motorized automobile. Therefore I cordially request you to transfer from your subterranean reservoir a sufficient quantity of the combustible fluid of the highest octane rating to fill the appropriate receptacle of the said means of perambulation to the brim.

Fuel Attendant: Oga na play I dey play o, how much fuel you wan buy?
