With Frank Mir going down to a motorcycle injury, this is the match that propelled Arlovski from interim UFC champ to the undisputed heavyweight champion. It also placed him firmly in the record books. Paul Buentello was no slouch. He'd won 6 straight coming into the bout, and had faced the likes of Dan Severn, Bo Cantrell, Evan Tanner, Mike Kyle, Ricco Rodriguez, and others. And while he didn't win all of those (and frankly, who didn't fight Dan Severn back then?), he came to fight. So Arlovski putting him down in 15 seconds to mark the fastest title fight KO in UFC history? Well, that's a top moment! And remember when Arlovski had long hair?
