Shaun White has completed his Olympic comeback, winning a gold medal in men's halfpipe at the 2018 PyeongChang Winter Olympics. It was about as dramatic of a win as you could have asked for.
After his first run, where he scored an impressive 94.25, White was so pumped he threw his helmet into the crowd. The run itself would have earned him a medal, even if he didn't later improve on it. However, when the celebrating was done, he realized he needed his helmet back for the next two runs.
He walked to the crowd and asked if he could have it back.
