First. Someone pooped. Without mom knowing.
Then, Nash found the poop.
Then, Nash ate the poop.
Then, Nash puked the poop on dad's chest.
Dad identified the puke as poop.
Mom promptly ran to the bathroom and puked.
Luckily we are equipped with a sense of humor. And a baby tooth wipe. Which was just waiting for such an occasion.
The real question is, whose poop was it?
