Wait, I have a real one! Seeing as you and your partner are a bit more stacked in the X chromosome department than is generally conducive to reproduction amongst yourselves, how did your little bundle of joy come to be? Adoption, or did one of you do the pregnancy thing? Genuinely curious.
To fulfill my end, I had sex with my wife at least twice (that I recall) and she gestated and delivered the beasts (C-section each time, not by choice).
