To make sure Brie Ann had quads, Tyrone masturbated into petrie dish, causing it to overflow. The doctor collected five eggs from Brie Ann and fertilized them in petrie dishes with Tyrone's generous sperm and implated the fertilized eggs in Brie Ann's womb. Since she was carrying the children for others, she was now a surrogate mother even though the eggs were hers. All five matured to term and Brie Ann made five ladies happy nine months later.
There was a question about the legitimacy of these children as Tyrone and Brie Ann had never married.
