Eccentric Swiss Iouri Podladtchikov upstaged USA star Shaun White to take the snowboard halfpipe gold medal in Sochi.
White's bid for a hat-trick of Winter Olympics halfpipe titles ended in failure as Podladtchikov proved the biggest crowd pleaser on Tuesday night.
The American was the red-hot favourite to add another crown to the ones he won at Turin 2006 and Vancouver four years later, but the 27-year-old could only finish fourth.
Instead it was Podladtchikov, nicknamed IPod, who took the glory, with Japanese 15-year-old prodigy Ayumu Hirano earning silver and his compatriot Taku Hiraoka bronze.
A jubilant Podladtichikov, referring to his gold medal, chose to paraphrase the Sochi Games motto of ''Hot, Cool, Yours'' when he said: ''It's hot, cool and it's f****** mine.''
White, nicknamed The Flying Tomato, had put down a score of 95.75 in the qualifiers to move straight into the showpiece event, but could not replicate that, and an error-strewn final run saw him awarded 90.25, which was not enough to claim even a podium spot.
''I'm disappointed,'' he said. ''I hate the fact that I nailed it in practice, but it happens. It's hard to be consistent.''

Austria's Daniela Iraschko-Stolz out-jumped the eventual winner with a second round leap of 104.5m but dropped more points on style and had to settle for the silver medal.
Coline Mattel of France took silver while the 17-year-old Takanashi, who was third after a first round jump of 100m, fell to fourth with a second round jump of 98.5m.
