Sure, the first time you see people playing soccer while riding bicycles, it looks awfully strange. But on the other hand, baseball probably looked ridiculous the first time people saw it, and now, it’s a national pastime. What makes cycleball great is that it doesn’t require any special equipment that the average sports fan doesn’t already have: to make a game work, all that’s needed is one bicycle per player (pros modify theirs a little, but you can make it work), a net, and a ball that’s sturdy enough to get the crap kicked out of it. The rules are pretty similar to soccer, so it’s not a steep learning curve.

Though cycleball might sound like something a bunch of teenagers made up for a silly YouTube video, Wired explains that it actually has a long history. Europeans have enjoyed cycleball since the late nineteenth century, though it has traditionally been known as “radball.”

Take note that if you want to take your cycleball game to the next level, you should modify your bike. Official radball bikes have their handlebars positioned straight up, and the bikes are locked into fixed gear so players can ride backward without skipping a beat.

We do thumb wars in elementary school, then we graduate to arm wrestling. All of this is pretty silly, but why would anyone presume that the body part championships have to end there? While nose wars haven’t yet become a thing (that we know of), there are some circles where “toe wrestling” is considered a serious sport. And yes, there’s a World Toe Wrestling Championship. It takes place in Derbyshire, England, and according to Reuters, England always wins.

Competitors get their feet rubbed before a match, in order to loosen up and relax their foot muscles. When the game is on, toe-fighters lock big toes and see who can pin the other person’s foot down. Though men and women both compete, battles between the sexes are not allowed.

The annual tradition was kicked off by a pub landlord in 1976, so it’s got a few decades of history behind it. One can only guess how long the trail of broken toes is. Just ask Alan “Nasty” Nash, the 2017 World Champion. According to CBC, Nash claims to have once broken four toes in the semi-finals and still battle on to win the finals. Now there’s a guy who can stand on his own two feet.

No, sorry. No matter how thrilling that new Netflix series might be or how fast your heart pounds when you’re playing a first-person shooter, you don’t get to consider sitting down a sport. Spending hours of the day plopped in a chair without any form of stretching or lifting, is terrible for you. But if you’re intent on finding a way to transform sitting into an athletic activity, then this might be the sport for you.

This is the art of “hockern,” also known as extreme sitting. While the English name sounds like dumb college humor, hockern devotees take their sport quite seriously. Rather than using office chairs or beanbags, extreme sitting involves a specialized stool called a “sporthocker,” which according to The Australian, was created by the dynamic German duo of Stephen and Michael Landshutz. According to Wired, the key to being a successful hocker is to do a lot of cool, crazy tricks with the sporthocker, and then finish it off by successfully planting your butt on the stool. So the “extreme sitting” is what you do at the end, not the beginning. Got it?

Anyhow, hockern has reportedly become a trend in its German homeland, with contests held across the country. In 2011, the sports industry trade show ISPO said that the popular stool had become “more than just a product. It is a movement, a trend, a new sport.” We’ll see!

Mixed martial arts, better known as MMA fighting, can be brutal. That’s kind of the point. However, no matter how bloody an MMA fight might get, what makes it a real sport is the existence of rules, regulations, judges, and the fact that the gloves of the competitors aren’t mini Tasers. If you want that, check out “shockfighting,” MMA’s mega-ultra-extreme nephew.

Shockfighting doesn’t seem like a very official sport, but it’s wacky enough to talk about. It is to MMA what the forgotten/reworked character of “Buzz Bunny” was supposed to be to Bugs Bunny, though we’ll see if it lasts any longer than Buzz did. Given that shockfighting involves people violently zapping each other, the odds don’t look great. Electricity punches are fine for Marvel villains, but in real life, the results can be horrifying.

For what it’s worth, MixedMartialArts.com doesn’t approve, calling it “trash MMA.” Others have referred to shockfighting as “the craziest, most barbaric sport man has ever created.” That might be going a bit far, considering that ancient Romans used to cheer at actual death matches. Still, shockfighting is pretty scary.
