From the Wiki page:
Curse of the Colonel – refers to an urban legend regarding a reputed curse placed on the Japanese Kansai-based Hanshin Tigers baseball team by deceased KFC founder and mascot Colonel Harland Sanders.
The curse was said to be placed on the team because of the Colonel’s anger over treatment of one of his store-front statues, which was thrown into the Dōtonbori River by celebrating Hanshin fans following their team’s victory in the 1985 Japan Championship Series. As is common with sports-related curses, the Curse of the Colonel was used to explain the team’s subsequent 18-year losing streak.Some fans believed the team would never win another Japan Series until the statue had been recovered.
Comparisons are often made between the Hanshin Tigers and the Boston Red Sox, who were said to be under the Curse of the Bambino until they won the World Series in 2004.The “Curse of the Colonel” has also been used as a boogeyman threat to those who would divulge the secret recipe of eleven herbs and spices that comprise the unique taste of his chicken.
