The Icelandic handball team happens to be kicking ass and takin' names right now! But ktsp already mentioned that...
I'm a fan of any of my 3 nationalities (+ Lebanon, my adopted one) winning any medals.
That said, in Iceland they aren't showing much of anything on the one channel that we have... mostly because they only show it live (we're 8 hours behind Beijing), which is in the middle of the night for a lot of things. So I might have settled for at least NBC so I could see SOME events... alas, I can't even watch on NBC's stupid website because my computer is not in America.
Mostly, though, I would love to watch the rowing events... there's no sport more beautiful than that, in my biased opinion. But they very rarely show it.
