My cousin recently gave birth to her third boy. Having grown up the oldest of three boys and seen the effect it's had on my mother, I personally think anyone who has two boys and would risk having a third is a fucking idiot. But I digress.
Anyway, I went to visit the birth suite and as the middle child (Miles) was holding his newborn brother in his lap, the following dialogue ensued:
Miles: "Mommy, does he have a penis?"
Mommy: "Yes Miles."
Miles: "Mommy, does he have a butt?"
Mommy: "Yes Miles, just like you."
Ten seconds of silence.
Miles: "Mommy, does he poop?"
Mommy: "Yes Miles."
Me: Laughing my ass off.
