"He is from Great Britain, but he’s lacking appropriate manners."—Vitali Klitschko after being slapped

"The hardest thing I have ever done was not break his face."— Wladimir Klitschko after being spat upon

Dereck "Del Boy" Chisora has a reputation for pre-fight weirdness having once planted a wet and meaningful kiss on the lips of hardly fetching opponent Carl Baker in a weigh-in situation. His behavior almost sparked a mini riot. More importantly, it was a prelude of things to come.

Chisora was suspended for mistaking the ear of limited Paul Butlin for a McNugget during their 2009 contest at the York Hall in Bethnal Green. As a result, the hungry but financially-challenged Chisora missed out on his fight for a British title against Danny Williams. He was also fined £2,500.

For the more recent Vitali slap heard ‘round the world and perpetrated while wearing a Union Jack mask, the weirdness continued as WBC president José Sulaimán described the slap as "an absolute disgrace." Thanks, Jose, for your salient point.

Seemingly intent on finding a bottom to his behavior, Del Boy then spat a rather large amount of liquid (hopefully water) into Wladimir’s face before the Vitali fight. Just when you thought Chisora couldn’t reach any lower, he did.

Oh yes, the lowbrow behavior from this loose British cannon is all quite apart from his being convicted of beating up a girlfriend.

But the madness had legs. On Saturday night, after Vitali Klitschko’s 10th successful defense of his WBC heavyweight title ended, chaos erupted when Chisora brawled with fellow loon and former WBA champion David Haye during the post-fight news conference. Chisora made fun of Haye’s toe. The brawl was witnessed by the Klitschko brothers who stood at the dais in wonderment. Del Boy still faces a charge of simple assault but he is allowed to return to England for now," police spokesman Gottfried Schlicht told AP on Sunday. British Boxing Board of Control general secretary Robert Smith indicated the governing body would launch an investigation.

I can’t find the butt, but it was a beauty. Del Boy launched a billy goat that would make Holyfield blink.
