Three year old Johnny had been in the bathroom for a long time and his mother went to check on him.

He was just sitting on the toilet reading a book but every 30 seconds or so he put his book down, gripped the toilet

seat with his left hand and hit himself on the top of his head with his right hand.

After watching for a couple of minutes, his mother asked if he was all right.

I'm fine mommy, just haven't gone potty yet.

OK - "you can stay for a few more minutes but why are you hitting yourself on the head?"

Johnny replied "It works for ketchup!"
