Oh cry me a river, they beat the Yankees and won the World Series.
Teasing/taunting is a natural part of sports, especially for intense fans of rivalries like Yankees/Red Sox, or Yankees/Mets. My whole family consists of Met fans, and I always hear worse about Yankees, Yankees' fans, Steinbrenner, pick any player and how he looks like a monkey, my mom has bad nicknames for all the players, etc.
Then you learn to deal and have fun pointing out fallacies in their taunting. Like in 2001, during spirit week, one of our days was wear your favorite teams' sports jersey day. So a particularly cocky Met fan came up to me in my Yankees' jersey and said, "so wearing that jersey of the team that didn't win the World Series, huh?" Me: "Yup. So are you." Him: "that's...uhh...umm...true."
"If there was a Mount Rushmore for Broadway scores, "West Side Story" would be front and center. It snaps, it crackles it pops! It surges with a roar, its energy and sheer life undiminished by the years" - NYPost reviewer Elisabeth Vincentelli
