It doesn't matter who you are, nobody approaches the President of the United States without permission.
A.J. Mass served as Mr. Met from 1994 to 1997, which meant he was present for former President Bill Clinton's visit to Shea Stadium for the 50th anniversary of Jackie Robinson breaking MLB's color barrier. In his new book, Yes, It’s Hot in Here: Adventures in the Weird, Woolly World of Sports Mascots, Mass reveals a pretty interesting experience.
Although Mr. Met is at games to have fun, he was given strict orders by a Secret Service agent to steer clear of Bubba, according to Mass. Via CBS New York:
"Now listen to me very carefully. ... We have snipers all around the stadium, just in case something were to happen. 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 Secret Service doesn't make any exceptions.
