A little boy walks in to the lounge one Sunday morning while his Dad is reading the paper. "Where does poo come from?" he asks. The father feeling a little perturbed that his 5 year old son is already asking difficult questions thinks for a moment and says: "Well you know we just ate breakfast?" "Yes," answers the boy. "Well the food goes into our tummies and our bodies take out all the good stuff, and then whatever is left over comes out of our bums when we go to the loo, and that is poo." The little boy looks perplexed, and stares at him in stunned silence for a few seconds and asks: "And Tigger?"
