When we were building the Houdini prototype, we were finally ready to start trying to play it, so we grab a bunch of balls from the factory where Magic Girls was being built, and drop them in. We start to play and we run into issues with the ball trough not properly moving balls through it and ejecting, we open things up, take it apart all looks good, but it is too tight. You obviously all see where this is going, not sure how long it took before we figured out that one of the balls was a bingo ball (why there was a bingo ball in the factory, is anyone's guess), and that extra 1/16 was enough to not let it move through correctly. I've kept the ball handy, never know when the opportunity to mess with someone will come up, but since I never knew it was supposed to be a bingo ball, guess I'll put it into my centaur.
