A little girl walks up to her dad asking:
"Dad, where does POO come from?"

The father was surprised with such a complex question.
" You know how we just ate breakfast?"

"yes" said the girl

"Well the food goes into our tummies, and our bodies take all the good stuff.
Whatever left comes out from our ass when we go to the toilet and that's POO."

The little girl was shocked, her eyes were watery, and was about to cry as she asked...

"And Tigger?"
