I saw one with Parker Bohn.  About 30 feet down the lane there are 4 pins spread out (like where the 7, 8, ,9 and 10 pins would be) and then there are 4 more pins stacked on top of those pins.  Parker stands at the foul line with his back to the pins, and just throws a ball over his shoulder without looking.  The ball rolls down the lane, and goes between the "7 and 8," knocking over all 8 pins.  All without looking.

But I don't know; this was pretty cool too!
