I don’t play Magic: the Gathering, but I like this story. Richard Garfield, who created the game, also made this special card and put it in his deck when he was playing with his girlfriend Lily Wu. When he played the card, he proposed (she accepted).
The best bit about the story is that, supposedly, it took four games for a situation to arise where he could legally play the card. A lesser man would’ve just shown her the card – but damn it, that wouldn’t have been legal.
