The "move heavy furniture as fast as you can through a narrow hallway for hours, while other people do the same thing in the opposite direction" challenge was such a retarded idea, I knew this would happen the moment Sam described it. Despite not being involved in shattering the coffee table (which happened 5 minutes into the contest), TJ has managed to cut his hand. Ben bandaged him up and he's fine. Sometimes, production being retarded is what makes the tank a uniquely funny show.
I'm pretty sure it was Shinji, not Jimmy, who was carrying the table with Duanye when it broke, but I'm not positive.
Edit: It was TJ who broke the table with Duanye but he cut himself later when he was trying to clean it.
