Sabrina: Potty Mouth

This morning, as I was changing Sabrina's diaper, she said:
"Ewww.  Wet!  [Singing] Wet wet wet wet wet wet wet wet wet.  [Talking] Me singing Wet Music Song."

This evening, here's our conversation:
Sabrina: Everybody in my bum!
Me: Excuse me?
Sabrina: No.
Me: What did you say?
Sabrina: Everybody in my bum!
Me: What does that mean?
Sabrina:  Poopies in my tummy go WOOOOOO!
