Mayor Rahm Emanuel said today that a goat's head dropped off at Wrigley Field is no laughing matter, but tell that to Cubs players.

"Come up with something original," scoffed Cubs pitcher Jeff Samardzija, noting that the billy goat curse against the team "has only been around for 60 or 70 years. You would think they would come up with something new."

"I don't have many thoughts on that," said Cubs manager Dale Sveum. "It's just some unfortunate fan doing something crazy. I spent two years in Boston, so I have a pretty good idea of the passion of the fans and the willingness to want to win."

Cubs first baseman Anthony Rizzo added, "In my opinion, it's just dumb. But it is what it is."

A man drove up to the ballpark around 2 p.m. Wednesday and handed a package to a security guard at Gate K, according to police and Cubs spokesman Julian Green.

The man asked the guard to deliver the package to Ricketts, then got back into his truck and drove away, police said. Security officials found the goat's head inside. The head was all black and had a U.S. Department of Agriculture tag on its ear, police said.

The package did not contain a note and was never delivered to Ricketts, police said. The head was taken to the city's Animal Control department, police said.

At an unrelated news conference today, Mayor Rahm Emanuel said he talked to Ricketts Wednesday night and promised that police will take action.

"There's nothing else to say, it speaks for itself, it's wrong to do," Emanuel told reporters. "I did call Tom last night, and said obviously that the police need to do something, we'll be on it."
