I was playing Scooby Doo on location and had just noticed the cool way the ball dumps out through the secret passage near the flippers.
All of a sudden the left flipper button felt strange, my left flipper finger was now inside the machine! The button fell out. A nice lady pointed out that it fell into the cup holder. I was able to throw it back in and play through.
This was a new one for me, has this ever happened to anyone else on such a new machine?
