Earlier today (Sat., Feb. 18, 2012), Dereck Chisora lost a unanimous decision to Vitali Klitschko over in Germany in a heavyweight bout that was far better than expected. Klitschko was his usual self, winning the bout without much issue, but Chisora was aggressive and put on a far better performance than most do when up against the heavyweight champion.

That's the boxing portion of the night. You know, the actual fighting. The entire evening was marred, though, by various acts of lunacy on Chisora's part, including an incident that saw him spit water in Vitali's brother Wladimir's face before the fight and another where he threatened to cancel the bout altogether over a hand wrapping issue.

Then, when all was said and done inside the ring (which was a mess after the bout with all sides still going at each other's throats), the post-fight press conference happened. And as you can see in the video above, it quickly devolved into madness.

David Haye was in attendance and he was egging on Chisora, who responded in kind. Eventually, they got in each other's faces and an all out brawl broke out. Not long after, Chisora made death threats, telling Haye and anyone else who was listening that he was going to shoot him. Police have reportedly got involved and the entire ordeal is one big mess.

Who said heavyweight boxing was dead?
