With my grandson, instead of telling him I got his nose showing him my thumb between my fingers, as he's much too smart for that, I tell him that I got his kidney. Then I squeeze out a chicken liver I had hid in my hand.
He can go look in the mirror if he wants and he still can't tell if I got it or not.
But once he drives himself down to the hospital, they'll straighten him out!
