“Last year, a newly married woman offered me 3 million naira to impregnate her.
According to her, she didn’t want her children to take her husband genes, because he was short, bald and his family had traces of ancestral madness,you know all these? why marry the man?
Dear men;
I heard DNA is now between 50-100k.
You don’t need to inform your wife – just take strands of your children’s hair while they are asleep and present them at the hospital.
There’s a huge chance that more than half of your children are not yours.
