Are you saying that you got a girl pregnant? And if so, how is that worse than everything my mistake ending up doing to me? Are you going to publicly tell me that your child is the worst mistake you ever made? That's just wrong.

No, silly. He means that's what the sperm who created him (i.e. his father's sperm) was thinking when it reached his mother's egg, and that was his worst mistake. It's supposed to be self-depricating humour, not Nominus actually having a child. No need to be so touchy.

Ah, you'll get used to it.
