What is the curse of the goat on the Chicago Cubs?

The Curse of the Billy Goat, or Billy Goat Curse is the name of an urban myth, superstition, used to explain the World Series drought that Major League Baseball's Chicago Cubs have had to endure since their last appearance in the 1945 World Series, and their last World Series championship in 1908. The curse is a classic example of a scapegoat. As the story goes, Vasili "Billy Goat" Sianis, a Greek immigrant who owned a nearby tavern (the now-famous Billy Goat Tavern), had two 7.20 USD box seat tickets to Game 4 of the 1945 World Series between the Chicago Cubs and the Detroit Tigers, and decided to bring his pet goat, Murphy (or Sinovia according to some references), with him. Sianis and the goat were allowed into Wrigley Field and even paraded about on the playing field before the game before ushers intervened. They were led off the field. After a heated argument, both Sianis and the goat were permitted to stay in the stadium occupying the box seat for which he had tickets. However, before the game was over, Sianis and the goat were ejected from the stadium at the command of Cubs owner Philip Knight Wrigley due to the animal's objectionable odor. Sianis was outraged at the ejection and allegedly placed a curse upon the Cubs that they would never win another pennant or play in a World Series at Wrigley Field again and left the States to vacation in his home in Greece. The Cubs lost Game 4 and eventually the 1945 World Series, prompting Sianis to write to Wrigley from Greece, saying, "Who stinks now?" Following a third-place finish in the National League in 1946, the Cubs would finish in the league's second division for the next 20 consecutive years. This streak finally ending in 1967, the year after Leo Durocher became the club's manager. Since that time, the cursed Cubs have not won a National League pennant or played in a World Series --the longest pennantless drought in Major League history. Sianis died in 1970. The Billy Goat Curse In 1945, William "Billy Goat" Sianis tried to bring his pet goat, Murphy, with him into Wrigley Field for Game 4 of the World Series. Ushers at the game said the goat was too smelly and told Sianis he had to leave. To retaliate, Sianis cast a "goat curse" on the Cubs by saying, "Cubs, they not gonna win anymore". The Cubs lost the 1945 World Series to the Detroit Tigers and haven't made it to a World Series since.
