When the Villan Ti Lung has just freed himself from his chains in prison. several huge crossbow bolt are fired at him. To help his escape he hurtles 4 into the air and then kicks them to stick into the wall so he can use them to climb the walls. BUT although he flips 4 bolts into the air he only kicks 3, and seconds later you see 4 fly through the air and stick into the wall. The slip up is he only kicked 3 but 4 went flying.
