People have played sports for as long as humans have been alive. There are some cave drawings of wrestling matches that date back to about 3000 BCE. But humans have gotten more creative with their games over the years. These odd sports are just a few examples of what they've come up with:

Jolleyball

Jolleyball is like volleyball, but a whole lot harder. Players have to juggle during the game. How does it work? Each player starts with two balls. Then, another ball is served. Whoever catches the served ball must juggle all three balls. That person then passes one ball to a teammate or tosses it back across the net.

Juggling Triathlon

Triathlons have three legs: swimming, cycling, and running. But a juggling triathlon adds three balls that must be juggled during the event. Racers start with the "swuggle." They swim the backstroke with both hands out of the water and juggle. The next leg is "unijuggling." This is where racers use one hand to control a unicycle and the other to juggle. The final leg is the "joggle," with racers running while juggling.

Unicycle Football

Speaking of unicycles, unicycle football was created in Texas in 2008. The game can be played anywhere that works for the players' wheels. This includes everything from parking lots to playing fields. The quarterback passes the football forward once per play. But all other players must pass the ball backward to score.

Cheese Rolling

Imagine racing down a steep hill with an 8-pound (3.6-kilogram) wheel of cheese. That's what some runners in England do. They chase the cheese down a hill, and the first to cross the finish line at the bottom wins. What's the prize? The cheese. Sounds simple, right? But the hill is so steep that the cheese can roll up to 70 miles (113 kilometers) per hour. That's as fast as a car on a highway.
