When Peyton Manning hosted “Saturday Night Live” five years ago he wasn’t completely out of his element. He had acted in school plays and starred in several popular commercials. For Eli Manning, hosting SNL will be something very new. “Not much Broadway or acting (experience),” Manning said on Monday. “So this will be a new experience for me. I’m a little nervous about it, but excited also. It should be a lot of fun. It will take some work, but it should be something I’ll always remember.”
