One morning a little girl asks her daddy: "Where does poo come from?" Her daddy feels a little embarrassed that his five year old daughter is asking such an awkward question, but thinks for a moment and says: "Well you know we just ate breakfast?"
"Yes," replies his D/D.
"Well the food goes in to our tummies and our bodies take out all the good stuff, and then whatever is left over comes out of our bottoms when we go to the toilet - and that is poo."
The little girl looks shocked, and with tears in her eyes asks: "And Tigger?"
