Yes, well, we thought it might happen: the Yankees win the World Series. Again.
Yah boo sucks from everyone outside New York City and wild jubilation from half of the people in it (or perhaps somewhat more than half: the Mets don't have quite the same home town support).
Actually, that might be rather over doing it. The Yankees winning the world Series is perhaps a little like Manchester United winning something in soccer. They're both, in their respective sports, rather larger than the actual sports they compete in. Huge number of people around the world claim Manchester United as their team, just as any number of people who aren't really sure of the finer points of baseball claim the Yankees as theirs.
So perhaps there will be jubliation outside NYC as well as the Yankees win the World Series.
