A little three-year-old boy is sitting on the toilet.
His mother thinks he has been in there too long,
so she goes in to see what's up.
The little boy is sitting on the toilet reading a book.
But about every ten seconds or so he puts the book down,
grips onto to the toilet seat with his left hand
and hits himself on top of the head with his right hand.
His mother says: "Billy, are you all right?
You've been in here for a while."Billy says:
"I'm fine, mommy. I just haven't gone doody yet
Mother says: "Okay, you can stay here a few more minutes.
But Billy, why are you hitting yourself on the head?
"Billy says, "Works for ketchup."
