At an MMA event in London, welterweight Mike Garret caught Sam Heron with a lightning-quick kick to the face that ended his night just a second into the bout.

As Cagepotato points out, though, the clock in the video is slightly misleading. Although Garret hits Heron with a kick in one second, the fight isn’t officially waved off immediately. It takes the referee a few additional seconds to make that call. Whether or not Garret’s KO is a world record remains to be verified, but his victory dance is one of the all-time best.
