Jerzi: Mommy, mommy, turn down the radio i have to tell you something. (way excited)
Me: What?
Jerzi: Do you know that boys stand up to go pee and sit down to go poop and girls sit down to go pee and poop?
Me: O wow where'd you learn that? (seeming enthused)
Jerzi: I didn't learned it, i just know that. (very matter of factly)
