I don't really follow the SC community other than watching a few tourneys and Day[9], but there's some hot_bid guy (I guess from the TL forums?) I saw on some SC2 videos streaming Portal right now on justin.tv. Hoooooly ****, he is by far the worst Portal player I have ever seen. Stream currently has 1300+ viewers, and it's hilarious. For anyone interested:
Stream link
TL forum thread link
Apologies if this isn't the proper thread, but I didn't see a "random ****" thread in the SC2 forum.
EDIT: He just got to GLaDOS, so the stream's probably almost over. But there should be archived video on his page after it's done.
