Peyton Manning
Peyton Manning - 

You have heard, no doubt, of Peyton Manning's affinity for the word "Omaha." As he brings the Denver Broncos to the line of scrimmage.

It could be a decoy. It could be serious. He's not telling. But come Sunday next, at Super Bowl XLVIII, guessing how many times he's going to say it could win somebody some serious money.

The over/under on "Omaha" has been set at 27 and a half by the online betting firm Bovada.lv. It's just one in a series of what are called proprietary bets, that get set up around the game.

You choose "over" and he says it  28 or more times: You win. On the other side, if you choose "under" and he says it 27 times or less: You win.

 Kai says over. 32, to be specific. He also says: Broncos by a touchdown.
