Curse of Billy Penn

The Curse of William Penn (supposedly begun in March 1987) is an alleged curse sometimes used to explain the failure of professional sports teams based in the American city of Philadelphia, Pennsylvania to win championships in the late 20th and early 21st centuries. None of Philadelphia's four major sports teams (baseball, football, basketball and ice hockey) has won a championship in its respective league since 1983, when the 76ers won the NBA title.
