Never underestimate the logic of little boys.
So, one day a little boy was sitting on the toilet reading a book.
About every 10 seconds or so he put the book down, gripped onto the toilet seat with his left hand and then hit himself on top of the head with his right hand.
His mother, hearing the noise coming from the bathroom, opened the door, saw what her son was doing and said, “Thomas, are you all right? You’ve been in there for a while now”.
Thomas replied, “I’m fine, Mommy. I just haven’t gone yet”.
Mother says, “Okay, you can stay in there a few more minutes, but Thomas, why are you hitting yourself on the head?”
Thomas says, “Well Mom, it works for ketchup!”
As I said, never underestimate the logic of little boys.
