There was something about shooting galleries that brought out the mischievousness in me and my brothers, and other kids my age back then. Not only did we enjoy setting off all the targets with a flash camers - once we were playing the "squirt the clown's mouth and pop the balloon game" at Coney Island, and the guy working the booth was a jerk for some reason ( can't remember why). So my brothers and I came up with a plan, and when the guy started the game we all aimed at the same big stuffed prize, soaked it, and ran. So satisfying!
Also, on the riflery range at camp, we used .22 rifles. It was loads more fun to aim for the clothes pins that held up the targets, than at the targets themselves. When you hit one you got a satisfying burst of splinters.
Good times...
