@Snappy, I have seen skeleton competitions during the last two winter Olympics, but they were broadcast on the basic cable channels, not the main network. I think they're more exciting than luge, probably because that's how I used to sled myself back in the day -- headfirst.
I didn't understand the dynamics of luge when I first saw it on TV. I thought they were riding in a slot or groove the whole time. Now I realize the lugers are essentially lying down on a big bar of soap and sliding down a really slippery bathtub. I'm amazed they don't just fly out of the chute after the first turn.
