Out of the Mouths of Babes
Greg, the three year old, put his shoes on by himself. His father, Barry, noticed that the left shoe was on the right foot and vice-versa. He sat Greg down on a chair and said quietly, 'Greg, your shoes are on the wrong feet.'
He looked up at his father with a quizzical expression and replied, 'Don't mess me about, Dad, I know they're my feet.'
