The man who once dressed as the New York Mets mascot, Mr. Met, wrote in his new memoir that a Secret Service agent once warned him not to approach President Clinton at the ballpark or the agent will "go for the kill shot."

The New York Post reported that A.J. Mass worked as the team's mascot from 1994 to 1997. He recalls in his memoir, "Yes, It’s Hot in Here: Adventures in the Weird, Woolly World of Sports Mascots," Jackie Robinson's 50th anniversary at Shea Stadium, which was attended by Clinton in 1997.

He writes that the agent told him that they have snipers around the stadium. Mass recalls the agent saying, "Like I said, do whatever it is you normally do. Nobody will bother you. But approach the president, and we go for the kill shot. Are we clear?" The agent repeated the line twice, Mass writes.
