The last time me and a few friends of mine went bowling we got 287 points... combined... between 4 people, I alone got 69 points (nice) and even managed to roll the ball into the arm after getting a gutter ball, thus causing it to realize I rolled, but then it knocked down all the pins to reset them, and since it registered that I already rolled it counted it as a spare (also the ball ended up stuck in the gutter).
