A little 3 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.

His mother says, 'Billy, are you all right? You've been in here for a while'.

The little boy is sitting on the toilet reading a book, but about every 10 seconds or so he grips onto the toilet seat with his left hand and hits himself, repeatedly, on top of the head with the book.

Billy says, 'I'm fine, Mommy, I just haven't 'been' yet'.

Mother says, 'Ok, you can stay here a few more minutes, but, Billy, why are you hitting yourself on the head?'

Billy says, 'Well, it works for Ketchup!!'
