Brawl Week: A Korean Baseball Fight

I just finished Ross Bernstein's The Code: Baseball's Unwritten Rules and Its Ignore-at-Your-Own-Risk Code of Conduct and it got me to thinking about the role that brawls play in baseball. Like many fans, I think today's hitters have gotten much too comfortable on the inside of the plate and are far too quick to rush the mound. Still, I have to admit, I get an adrenaline rush every time I see a baseball brawl.

I went out to You Tube to see if I could find any video of my favorite brawls, but it looks like MLB has cracked down on baseball stuff showing up on You Tube. Still, I found this video of a Korean baseball fight. Does anyone have any idea what is going on here?
