The illegitimate father, LMAO

Ken. had just finished his national youth service and went straight to his father and said. "Daddy, Nkechi and i wish to be married soon". "Sorry Ken. Replied the father You can"t, Nkechi is your sister although your mother doesn"t know this." A day or two later Ken summoned courage and went to his mother and said. "Mother, what do you think about Nkechi she and i are planning to get married". Why not? Nkechi is a pleasant girl. Yes, but daddy says she"s my sister. "she"s not your sister, Ken, only your father doesn"t know he"s not your father.
