[dang], the Yankees can't win in anything anymore, can they?
Hilarious.
I've got to say that as a Boston transplant now living in the Bay Area that the sentiment is more or less correct -- Boston teams are not liked. From what I can tell, it is mostly due to what I believe are called the "pink hat brigade" -- you know, all those post '04 Red Sox fans.
I try not to let any of it bother me. I often root for teams other than the Boston ones (so long as they are not playing a Boston team), and always seem to have a thing for the underdog. GSW playing against Dallas was a case in point. Warriors last spring = big underdog + fun-to-watch team.
