Sippy Cup (smiling): "Hey Dad, let's play 'Rock, Paper, Scissors' again!"
Me (putting my book down): "Ok. But I should warn you, I've learned from our last game. I'm playing by your street rules now."
Sippy Cup (still smiling): "Ok!"
Me (nervous): "Your smile worries me. But let's do this!"
Sippy Cup (pounding his little fist into his open palm): "Rock, paper, scissor, shoot!"
Me (holding up a finger gun): "Ha!"
Sippy Cup (holding up his palm, similar to a traffic cop directing traffic to stop): "Ha! I win!"
Me: "What? How is that possible? You held up paper! I'm pretty sure a gun beats paper!"
Sippy Cup (switching his hand to a palm up/"low five" position): "Nope, this is paper!"
Me: "So what was that other thing?"
Sippy Cup (reverting to his original palm forward position): "This? This is a bullet-proof vest!"
