Where does pooh come from Daddy?

A little lad says to his dad “where does pooh come from Daddy”?

“Well son, when you eat food it goes into your tummy where it gets broken down. Then it goes into your large intestine where all the goodness is extracted. Then it goes into your small intestine and finally it gets to your rectum. Eventually it comes out of your bottom”.

“Gosh Daddy, that’s amazing. So where does Tigger come from then”?
