The boys were playing the Pokemon card game this afternoon. Andrew, being a good big brother, tried to explain the intricacies of the game to Michael.

Andrew - "Okay, Michael, this [something, something] means you can't hurt this card right now. Okay?"
Michael - "No, I want that card."
Andrew - [voice rising] "No, Michael you can't fight that one right now; he's not in the game. You can't hurt that pokemon."

Michael - [voice louder than Andrew's and to the sound of a card being ripped in half] "Yes, I can."

We don't need no stinkin' rules...
