I had something like that happen. Played the pinball game that gets loaded on a lot of computers, and the ball ended up in a scenario where it went into one of the top holes where it got points, and every time the hole would spit the ball back out, it would just ricochet back into the hole, causing a point-farming loop. If you see a phone number among the high scores, that would be me, and I was watching Yu-Gi-Oh the whole time.
