You guys should do a high speed slo-mo video of that trick shot where you have a ball in each corner pocket where a guy stands at the ball well and puts a finger on each ball. Meantime, there's a nickel somewhere near the foot spot and you hit the CB hard towards the nickel and the CB flies up and hits the guy in the nuts.
You should hit the shot at different speeds, spins and cue elevations to see how each variable affects the guy's nuts.
