Tertius approaches me with a pack of cards and invites me to pick one. The nine of hearts. I memorize it, then slide it back into the deck. He shuffles through, produces a card, and asks me if it's mine. It is indeed. And I choose not to mention that I know he owns a trick deck in which the nine of hearts is, shall we say, overrepresented.
Later, he insists that I play "Go Fish" with him. He solemnly deals out seven cards. I look at them. They're all the nine of hearts. "Got any nines?" he shouts gleefully, getting in just ahead of me.
