Mark Zupan, star of wheelchair-rugby docu Murderball (which, you'll remember, was a hit at Sundance), is keeping a blog at MTV.com. He and some friends are touring the country promoting the film - and they're hitting parties, talking to fans, quoting Weezer, and eating "badass Ahi tuna sandwiches" in the process. He also drops a couple of details on the episode of Jackass the shot with the rest of the Murderball guys: "I don't want to give too much away," he says, "but let's just say that Steve-O has a really big black eye today."
