Yes, it's funny until it happens to you, right? Well, unless you're a star of one of the clips below, then you have nothing to worry about. This video showcases the remarkable variety of unfortunate humans that populate the Earth.
Some believe they have more skill than they actually have. Just take the one dude on his BMX who thinks he can make the jump from one ramp to another. For that to work, one requires momentum, something that guy clearly doesn't understand.
Another case of pure-class is the spotty teenager on a rollercoaster. Perhaps he didn't know what to expect, after all, coasters can be unpredictable. Either way, the loop of him freaking out, passing out, waking up, freaking out, passing out and waking up is hilarious.
Then, it's time for grampa and those elusive-to-master hoverboards. It's a perfect example of how to break a hip. Grandpas are good at falling over though, so we'll give them that. Just check them out in action in a 50-metre sprint... at least some of them made it to the finish line.
Special mentions go to wedding days, sports fans, narcoleptics and animals. Just hit that play button below for hilarious fails that'll make you cringe.
