What's the weirdest Olympic sport?
Well, there's beach volleyball and synchronized swimming and rhythmic gymnastics, but there's also one you've probably never watched before. We're talking about modern pentathlon.
"Nobody, like, wakes up in the morning and thinks, 'Right, I want to be a pentathlete,'" British modern pentathlete Samantha Murray said. "It's just such a random mix of sports."
Modern pentathlon has five components: fencing, swimming, show jumping, running and shooting.
Did we mention the shooting and the running happen at the same time? And since the 2012 Olympics, the runners just stop what they're doing and start firing at a target.
If you're wondering what the five events have to do with each other, there's a reasonable explanation.
When modern pentathlon broke into the Olympics in 1912, it was meant to showcase the skills needed for a good soldier: things like combat with swords, riding an unfamiliar horse and swimming and running over the course of battle.
But today, modern pentathlon is struggling to remain a part of the Olympic program — mainly because not that many people care about it.
"A lot of the rumors going into this meeting this week was that it was going to be modern pentathlon that was going to be dropped," Wall Street Journal reporter Stu Woo said. "Because who watches the modern pentathlon?"
In 2013 the International Olympic Committee surprisingly chose to drop wrestling from the Olympics, despite that sport's thousands of years of history. Many fans argue modern pentathlon should have been dropped instead.
Even though wrestling was put back in the games months after it was booted, modern pentathlon is still around, and how it got started is a big reason why.
It was created by the founder of the modern Olympics, Baron Pierre de Coubertin. He envisioned the sport as a sort of culmination of the games' athletic feats.
And even though that's not entirely how it worked out, the modern pentathlon still enjoys some of the Olympic spotlight. The flag bearer for the host nation Brazil at this year's opening ceremony was a modern pentathlete.
