Sam(3): Dad, I love you.
Dad: Aww, I love you, too.
Sam: I wish I could sit on your head.

As we prepare to leave for the donut shop at 5.30, Sam (3) grabs his penis like he needs to pee.
Dad: Is your penis telling you you need to use the potty?
Sam: No. My penis is telling me I need to go to the donut shop.
