A guy named AJ Mass wore the Mr. Met costume at Shea Stadium from 1994-97. He just wrote a memoir called “Yes, It’s Hot in Here — Adventures in the Weird, Wooly World of Sports Mascots.” In it, he reveals that in 1997, President Clinton visited Shea. Mass wanted to meet him, but the secret service was concerned about security because, let’s face it, you can put anything in a giant baseball head.

And they warned him:

“We have snipers all around the stadium, just in case something were to happen,” the agent warned. “Like I said, do whatever it is you normally do. But approach the President, and we go for the kill shot. Are we clear?”
