Where do babies come from?
A little girl asks her dad “Where do babies come from?” and the dad explains to her “Well, babies are made when two people love each other and then the daddy puts his penis in the mummy’s vagina.”
The little girl then asks “If that is where babies com from then what does mummy get when daddy puts his penis in her mouth?” He contemplated this for a while, before replying “Jewellery… mummy gets jewellery.”
