I love watching the Olympics! Normally I don't watch "sports" as I've never been any good at them but the Olympics are different for some reason. I just really enjoy watching them.
However, in most sports, the actual active competition bits are quite short. And in between competitors there are endless commercials and scads of obnoxious commentator banter. So while watching the Olympics I've also been watching Star Trek: The Next Generation from the beginning (using my laptop). Growing up I watched a lot of the episodes, but mostly out of order in reruns and certainly not all of them. It's geeky, but so far I'm really enjoying them.
