Anderson Silva has long been considered the best pound-for-pound MMA fighter in the world. But last night his cockiness came back to bite him when Chris Weidman knocked him out at UFC 162.

Silva was in the middle of taunting Weidman — dancing with his hands at his sides, specifically — when Weidman caught him with a left hook and KO'd him.

It's Silva's first loss since 2006.

He typically does a lot of this sort of stuff in his matches.
