Is that a real Sport?

There are some unusual sports out there. What ones confuse you?

Synchronized Diving: Like diving, but synchronized! The only sport in the world where if both athletes make a mistake, they still get points! But the fuck-up must be synchronized! The Hell?

Artistic Roller Skating: Like ice-skating, but without the ice. Or the blades, or Tonya Harding…

What’s with the Winter Olympic Biathlon….skiing and shooting…lovely. Is this from The Sound of Music outtakes?
