As if the Chicago Cubs needed any more motivation to end their century-long World Series drought, the franchise got some in the form of goat's head delivered to Wrigley Field on Wednesday.

The Chicago Tribune reported that a package containing an animal's head was dropped off at Wrigley Field and addressed to Chicago Cubs owner Tom Ricketts. Police quickly removed the package and are investigating the incident.

The prank is likely a reference to the fabled Curse of the Billy Goat. In 1945, the last time the Cubs appeared in the World Series, bar owner Billy Sianis was asked to leave Wrigley Field because the odor of his goat was disturbing other fans. As the story goes, Sianis was so outraged that he put a curse on the team, saying it would never win a World Series at Wrigley Field.

Over the years repeated attempts have been made to break the curse, including several others involving dead goats.

But, alas, the Cubs have still not won the pennant since 1945.
