A little girl walks up to her father and asks
"Daddy, where does Poo come from ?"
The father a little embarrassed decided it was time for his girl to learn about the human body and proceeded to explain the whole process.
"Well darling, when you eat food, your body takes all the nutrients and converts them to energy and vitamins, what is left is created into poo"
The girl horrified then asks
"And what about Tigger"?
