As all fish throwing cognoscenti know the pinnacle of the sport is the Australian Tuna Tossing event. However, at the North Carolina Seafood Festival (a celebration of everything from shrimp to shark!) they are known to play a marvellous version of Flounder Flinging.
All you need to play is a bowl to make a target and someone to form the baseboard. This person sits down, legs apart and with the bowl on the floor between them. Competitors take turns to toss the flounder so that ideally it hits the human baseboard in the face and then flops into the bowl.
If you play an odd game or sport, maybe a version of baseball involving a jellyfish and catfish then Strange Games would love to hear about it. E-mail Montegue at firstname.lastname@example.org
