No shortage of prop bets for SB XLVII

Every year, the Super Bowl brings with it a host of sideshows that have become as ingrained in society as the game itself. From the commercials and halftime shows to office pools and big-screen TV parties, everything about the Super Bowl is arguably as big as the game's outcome.

Another one of those traditions is the increasingly popular host of prop bets set up by casinos — those goofy, offbeat bets, which often have nothing to do with the game itself, that help make Super Bowl Sunday the single biggest sports betting day of the year in Las Vegas. And Super Bowl XLVII is no different.

Will Alicia Keys blow the national anthem? You can bet on it. Got a few extra bucks burning a hole in your pocket? How about wagering on the color of Beyonce's top when she takes the stage at halftime? Will Jack or Jackie Harbaugh, the parents of the opposing coaches, wear anything sporting the logo of either team? You can bet on that, too.

Below is a sampling of some of the bets offered by the website Bovada.lv, most of which can also be made at any sports book in Vegas.

Note: Fractional odds are expressed as the profit a winning wager would return compared with the amount of the initial wager. So odds of 3/2 means a winning bet would return $3 profit for every $2 bet (for a total return of $5). Conversely, odds of 2/3 means a winning bet would return $2 profit for every $3 bet (for a total return of $5). A proposition with the larger number to the left of the slash is considered an underdog. Plus-minus odds are expressed the amount of profit returned on a $100 wager (plus odds) or the amount of money needed to be wagered to profit $100 (minus odds). So a winning wager with odds of +$150 means for every $100 bet a profit of $150 is returned (for a total return of $250 for every $100 wagered — or $2.50 total return on every $1 wagered). A winning wager with odds of -$150 means that in order to profit $100, a bettor must bet $150 (so for every $1 a bettor wants to profit, he must wager $1.50). A proposition with positive odds is considered an underdog; a favorite has negative odds.
