Conor McGregor talked a lot of trash in the days leading up to his UFC 205 fight with Eddie Alvarez. During the final press conference before the fight on Thursday, he attempted to attack Alvarez with a chair after showing up extremely late and berated him in front of everyone over and over and over again. On Friday, he took aim at another fighter Tyron Woodley during the UFC 205 weigh-in. And on Saturday night, he backed all the tough talk up at Madison Square Garden by completely overmatching Alvarez in the Octagon to become the first fighter in UFC history to hold two title belts—the featherweight belt and the lightweight belt—at the same time. McGregor beat Alvarez by a second-round TKO:

After the fight, McGregor continued to do what he does best by taking his two belts and talking more trash to, well, everyone. His post-fight interview was even better than the fight itself:

"I’ve ridiculed everyone on the roster, and I just want to say from the bottom of my heart, I’d like to take this chance to apologize to absolutely nobody," he said. "The double champ does what the fuck he wants!"
