Anger steps through the ropes with an impressive mix of old and new, including perhaps the biggest current poster boy for rage, the brawl-inciting Ron Artest. And his most angry contemporaries are also in the mix: "goon-it-up" hoops coach John Chaney and chair-throwing, player-choking coach Bobby Knight.
But don't forget the old-school examples like short-tempered former Yankees player and manager Billy Martin, Cardinals intimidator Bob Gibson and Raiders hit man Jack Tatum. Then you have the 'tweeners, those who practiced acrimony and fury in recent years but have since retired: sucker-punching linebacker Bill Romanowski, loudmouth pitcher John Rocker and "Super Brat" tennis player John McEnroe.
Today's benevolent souls are also taking part, from squeaky-clean quarterback Tom Brady and the stoic Tim Duncan to the charitable hearts of David Robinson, Alex Rodriguez, Phil Mickleson and Oscar De La Hoya.
