Where Did I Come From?

The other night, out of the blue:
Ross: How did you get me?
Me: Ummm, what do you mean?
R: How did you get a son?
Me: You came out of my tummy.
R: Oh. From your belly button?
M: (why wasn't I better prepared for this) No, from a different hole. Kinda by where I go potty.
R: Oh.

The next night, we were out for supper with Sister and Julie when Ross announced:

"I came out of my mommy's butt hole"

Mother of the year award, here I come.
