The first (or surviving) children you (or your spouse) have to replace you (and spouse if any) after you die.
We don't want to overpopulate the earth, so Jim and I plan on adopting after having our replacement babies, so after they murder us in cold blood, the world's population will go back to normal.

Get the Replacement Babies mug.
Definition 1: when your girl gives birth to your baby but it's damn ugly, so you replace it with a baby that looks cute and not like a forty year old man.
Definition 2: when your girl gives birth but you're not in need of a baby so, you replace it with a baby of another race, blame your girl and dip.
DEF 1: Friend 1: "yo you've got a really cute baby, congrats!"
Friend 2: "ye thanks, it was nothing a little "Baby Replace Jutsu couldn't fix.""
Friend 1: "WHA-"

DEF 2: Friend1: " yo, where is your baby, I thought your girl gave birth?"
Friend 2: "ye, it's funny cos after a bit of "Baby Replace Jutsu" it turned out the baby wasn't even mine!"
Friend 1: "what does that mean?"
