How to make the summer Olympics more efficient/entertaining:

 

Put contestants from Canoe Slalom, Rowing, Sailing, Swimming, and Water Polo into a large pond or small lake. Put contestants from Shooting on horseback with the Equestrian contestants; the Equestrian athletes will navigate the horses while the shooters try to kill anything moving in the pond/lake. Meanwhile, the Archery contestants will ride on the backs of the Cycling contestants bicycles; the cyclists will drive into the horse traffic and the archers will try to bring down the shooters with their arrows (the shooters can retaliate). In a nearby field, the contestants from Badminton, Fencing, Hockey, Tennis, and Table Tennis will all fight each other in an event known as "every man for himself" using the implements from their respective sports. The Volleyball contestants will be given clubs and the Beach Volleyball contestants will be given knives; they will each be told that the other team threatened to kill them, then they will battle. Judo vs. Boxing is self-explanatory. The Basketball players will be responsible for digging mass graves, the handball players will bury the remaining athletes, and the gymnasts will entertain the mourners by jumping over corpses.
