Peyton Manning ends retirement speech with one final 'Omaha!'

Among the many things Peyton Manning will be remembered for — his record 539 touchdowns and 71,940 passing yards, his two Super Bowls, and the ever-present purple mark on his forehead from his helmet — his mysterious signature pre-snap call "Omaha!" is something you don't yet realize you'll miss next season. At the end of his emotional retirement press conference Monday, Manning walked away from the podium only after delivering one final "Omaha" for good measure.

Manning never revealed what the call actually means, but gave a very coy explanation years ago.

Manning's former teammate Reggie Wayne pulled back the curtain last season on the NFL Network and claimed that "Omaha" simply means Manning is changing the direction of the play.
