I'm a shit.

Austin, Mom and Dad were sitting on the futon together after school on a weekday recently. Austin was chatting away impressing us with his crafty language abilities. Jo prompted him to say: "I'm a genius". He paused, and you could see him really thinking, and he surprised instead by saying: "I'm a shit." This comes from Dad (very rarely) prompting Austin to say "I'm a little shit" because of his precocious nature.
