In high school, I was pretty shocked when my mom sat down with me and my buddies to play Tetris. And she actually whooped on us.

What was going on became very clear to me when her only complaint was that the controls weren't on a keyboard; she could only have gotten that good by wasting her time playing the game at some old job or school.

It is also funny to note that she had no conception of the competitive aspect of the multilayer modernization of Tetris, even though she was flailing bricks at us the entire time.
