Haha. Reminds me of my high school phys ed class; one of the sections we had during the year was bowling. The school didn't have an actual bowling alley, so they had special bowling equipment designed to be used in a normal gym. This consisted of a set of bowling pins, and a hollow hard rubber ball with holes - it was the size of a normal bowling ball, but much lighter.
It didn't take us long to figure out that getting a strike was easier if, instead of rolling the ball across the floor as intended, we threw it in a shallow arc, so it landed right in the middle of the pins. Timing was everything, of course... you had to wait until the teacher's back was turned.
