JACK: Mom, I think we should buy a baby?
ME: (surprised and shocked) What did you say?!?!?
JACK: (nonchalant) I said I think we need to buy a baby!
ME: Where, exactly, does one "buy" a baby?
JACK: (in an authoritative voice) Mom, we buy one from the hospital. We go into the big hospital and go to the room where they keep the babies and pick one out and pay for it later.
ME: (thinking out loud) Yeah, we sure do pay for the baby.
JACK: So, how about it?
ME: Go ask your dad about that one!
