<laugh> I agree. I was very annoyed at the coverage from NBC in the US. They only show events if Americans are particularly good at them or athlete who has overcome some fantastic difficulty is competing. This left out most of the more interesting events (in my personal opinion) such as fencing and judo.
Perhaps there's no corresponding "mental olympics" because the mental 'sports' that we engage in are more suited to cooperation than competition - and cooperation is bad for ratings. :)
