[Harley's Dad]

A small girl went into the sitting room at home where her father was reading the paper.
"Daddy, where does poo come from?" she asked.
Father, feeling a bit perturbed that his five-year-old daughter was already asking difficult questions, thought for a moment and said:
"Well, you know when we just ate breakfast?"
"Yes," replied the girl.
"Well, the food goes into our tummies and our bodies take all the good stuff out, and then whatever's left over comes out of our bottoms when we go to the loo. That's poo."
The small girl looked perplexed and sat in stunned silence for a while. Then she asked "And Tigger?"
