The thing that immediately comes to mind is a cheap telescoping fly swatter. . Old radio antenna style shaft / handle. The part that’s supposed to swat the flies was a massive square that was way too heavy and had so much drag that it would flop and never hit flat and was too slow because of it. Never once was able to kill a fly and after about the fifth try the handle broke in half and the top flew off launching into the great Beyond. Pretty sure it’s still lodged behind a couch somewhere.
