David Clarkson is the New Jersey Devils' team enforcer. He's one of the top players with the number of fighting majors totaling 12 tying him with three other players for fourth place (as of 01/29/2009). His high for fighting majors throughout his entire hockey career (OHL, AHL, NHL) is 21 during the regular 2007-2008 NHL season. He's currently on track to surpass that high.
According to hockeyfights.com, he has won six of those fights with two others ending in draws and only four losses.
His best fight by far was on January 2, 2009 against Tom Kostopoulos of the Montreal Canadiens. Both players received 5-minute fighting majors, but it's apparent that Clarkson got the better of Kostopoulos here (it's a little slow-starting, but Clarkson gets some solid shots in within the minute the fight lasts).
