Sage Kotsenburg, a 21-year-old Olympic gold medal-winning snowboarder has blown minds again. Kotsenburg debuted his 1620 Japan Grab trick during the Winter Olympics last year, but had a new, unorthodox feat to display on Conan.

At 21 Kotsenburg is accomplished. He won the first ever men's snowboarding slopestyle in Sochi, Russia, and was the first gold medalist of the whole games. He won a silver medal at the 2012 Winter X Games in men's slopestyle, and took the bronze medal in the Snowboard Big Air at the 2011 Winter X Games.

Kotsenburg was promoting fellow snowboarder Shaun White's two-day Air & Style event, featuring some of the world's top winter sports stars as well as music icons like rapper Kendrick Lamar, DJ Steve Aoki, and many more artists.

The weekend festivities include three-round snowboarding and skiing competitions, snowboard and ski demos, as well as musical performances and meet and greets.
