We sparkle

I walked into the bathroom and found my son camped out. The following conversation happened:

Me: Pew wee stinky. I am glad girls don't poop!

Him: (Giggle) Yes you do!

Me: Nope. Never done it.

Him: (Giggle, giggle) Yes you do! I know you do! Where else would your food waste go?

Me: Girls sparkle it out. Ever time you see us wearing glitter that is our left over food.

Him: (he he, giggle giggle) Nuh uh. I know for a fact girls poop. I have a sister and she comes in the bathroom all the time.

Me: Is she not always wearing glitter or sparkles?

Him: (tee hee giggle) Yes but...what are stomach juices in girls so strong that they combust them into sparkles?

Me: That sounds about right?

Him: (flush and washes hands) Mommy that is just silly girls have to poop.

Me: Ever see it?

Him: (as he runs from the room) DADDY! Mommy's crazy! (runs screaming AHHHHHHHHHHH DOWN THE HALL)
