Curse of the Bambino

The Boston Red Sox won the 2004 baseball World Series. Apparently, this curse does not exist.

The Curse of the Bambino was an urban myth or scapegoat cited as a reason for the failure of the Boston Red Sox baseball team to win the World Series for 86 years after they sold Babe Ruth, sometimes called The Bambino, to the New York Yankees. The flip side of the "curse" was New York's success—after the sale, the once-lackluster Yankees became one of the most successful franchises in North American professional sports. While some fans that took the superstition of the Curse seriously, many others used the expression in a tongue-in-cheek manner.

The future of the phrase seems in doubt, since the Sox defeated the Yankees in dramatic fashion in the 2004 American League Championship Series and then won the 2004 World Series.
