Hundreds of millions of dollars will be bet on Super Bowl XLVII. Not just bet on who will win the game, but millions will be put on prop bets.

In most cases, silly prop bets. For instance, how many times will "Harbaugh" be said during the game. The over/under on that one is 21.5.

Other fun prop bets include the color of Gatorade dumped on winning coach: clear/water: +$200; orange: +$250; yellow: +$250; blue: +$700; green: +$700; red: +$700. If I knew the waterboy for either team, I'd give him a call this week, then I'd call a prop bet bookie.

How about prop bets on Super Bowl entertainment? Will Jay-Z and Beyonce ever share the stage during halftime show? Yes is +110, which is also the number on whether or not Beyonce's hair will be straight or curly.

Other prop bets that aren't as silly but could be fun to keep an eye on involve several players. Baltimore Ravens pro bowler Vonta Leach is stereotypical NFL fullback. A giant man who loves contact. How many combined rushing and receiving yards will he have? Over/under on that one is 12.5.

Do you think San Francisco 49ers quarterback Colin Kaepernick will get hurt? If you do, you might want to lay down a few apples on whether or not Alex Smith will take a snap from center? Yes is +500, while no is -700. Not a bad risk when you consider the 5-to-1 odds.
