Pulling off a backflip and landing safely on your skis is one thing.
What about doing it while holding someone's hand?
Or while holding the hand of the skier on your left and right?
In fact, what about 30 of you in a row simultaneously pulling off a backflip and everyone landing safely?
Incredibly, that's what Mikael Kingsbury, the 20-year-old world champion on moguls, decided to do - getting a group of like-minded individuals together to see if it could be pulled off.
It took some practicing, and their first full attempt ended in failure. But at the second time of asking, this was the beautiful result.
"We were pretty stoked," Jérôme Bernèche, one of the skiers, said afterwards. "I don't think anybody really expected it to work that well. We went for lunch [and] got a big poutine [typical Canadian dish] to celebrate."
