I think i've seen him write about something sports-related once on this site. Contributes nothing on here, although in his eyes he is the definitive expert on everything, and if you have a point, heaven forbid he actually read it only to discover a grammatical error or inconsistency in language and jump on that because he has no point. Guy is the biggest douchebag on the site and I doubt has ever made a bet in his life on sports that has won.
