what to watch for?

i'm looking for suggestions of what to watch for in the olympics. i'm not a t.v. watcher so the thought to turn on the television requires a bit of planning for me. last night my brother was watching some of the olympics and i saw a clip about synchronized diving. i had no idea that such a competition existed... and i was amazed at how aligned the divers were with one another. so, i'd love any suggestions for "must sees" in these summer games.

many thanks,
ashley
