Sledgehammers vs. fire extinguishers in S. Korean parliament.

Coolest Congress ever? Check the link for pics of the legislative mayhem:

Brawling MPs used sledgehammers to force their way into a parliamentary committee room in South Korea.

Opposition Democratic Party members wanted to get into the room to block a free-trade agreement with the US.

Ruling Grand National Party members fought back with fire extinguishers and fists as the country's parliament descended into chaos.

Scuffles broke out as dozens of opposition MPs and their aides attempted to push their way in to the committee room.

TV footage showed people from both sides shoving, pushing and shouting in a crowded hall at the National Assembly building, amid a barrage of flashing cameras.

Protesters used a sledgehammer and other tools to tear open the room's wooden doors, only to find barricades of furniture set up inside as a second line of defence.

The cable news channel YTN showed footage of security guards spraying fire extinguishers at those trying to force their way in, and one man with blood trickling down his face.
