U.S.A. All The Way

Hooray for the London Olympics!  Normally I'm not much of a sports fan.  I cannot tell you which channel is ESPN, however every four years I do my patriotic duty and support the U.S.A.  My favorite sports to watch are men's diving and men's water polo.  These two sports have a way of capturing my attention.  I wonder why?

And why is Rugby not in the Olympics?
