I was changing Katie's diaper...here's how it went:
Mommy: Whew-eee! That's a lotta poopie Miss!
Katie: Can I see?
Mommy: You want to see? OK. (show her the diaper)
Katie: From my bum?
Mommy: Yep, from your bum.
Katie: Chocolate from my bum?
Mommy: (after recovering from copious laughter) ummm...not exactly, no.
