At gigs I have fun by hucking drumsticks to my buddies in the audience and catching them when they huck ’em back at me (all while playing).
One time I hucked a stick at this guy by the side of the stage but he never saw it coming. The stick perfectly lopped off the top half of his beer glass without spilling one drop. The guy didn’t even know his glass was broken until he lifted his glass up to take a drink! He had no idea what had happened.
