The potty

h/t: Cyndi

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 15 SECONDS OR SO, HE PUTS THE BOOK DOWN, GRIPS ONTO THE TOILET SEAT WITH HIS LEFT HAND AND HITS HIMSELF ON TOP OF HIS 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 POTTY' YET."

MOTHER SAYS: "OK, YOU CAN STAY HERE A FEW MORE MINUTES. BUT,  BILLY,  WHY ARE YOU HITTING YOURSELF ON THE HEAD?"

BILLY SAYS: "WORKS FOR KETCHUP."
