"(CNN) -- A dreaded curse that has nagged Chicago's Wrigley Field for decades may have triggered a grotesque prank Wednesday, when an unidentified man in an unmarked truck dropped off a package containing a severed goat's head at the stadium.
The gruesome parcel was addressed to the club's owner, Tom Ricketts, CNN affiliate WBBM reported. While the delivery -- confirmed by the Cubs and caught on surveillance footage -- was certainly offensive, it's nothing new.
