Little Tommy was sitting on the toilet pot. His mother thought he was taking too long, so she went into the bathroom to check on him. Tommy was there sitting on the toilet seat reading a book. But every few seconds, he would put the book down, grab the toilet seat with one hand, and hit himself on top of the head with the other hand.
His mother found this strange and asked: "Tommy, are you okay? You've been in here for a while."
Little Tommy replied, "I'm fine, mom, I just haven't done my potty yet."
His mother said, "That's all right, sweety, you can stay here for some more time, but why do you keep hitting yourself on the head?"
Little Tommy replied: "Works for ketchup."
