Wikipedia defines a prop bet (proposition bet) as "a bet made regarding the occurrence or non-occurrence during a game (usually a gambling game) of an event not directly affecting the game's final outcome." Looking through some of the bets, they are quite ridiculous but making such wagers would make a game that more interesting. Here are some prop bets and odds from Bovada.
How long will it take Kelly Clarkson to sing the National Anthem?
Over 1 minute 34 Seconds -120
Under 1 minute 34 Seconds -120You would think over since singers tend to overextend the lyrics "home of the braaaaave" but I don't think she would milk it as much, say if Christina Aguilera were to sing it.
Will Madonna wear a hat at any point during the Super Bowl Halftime show?
No EVENThe only Madonna performance I ever saw was the one where see sang Vogue on MTV. Everyone had on Victorian dresses and I believe she had something on her head. Even though that was years ago, I'll go with yes to a hat.
How many times will Giselle Bundchen be shown on TV during the game?
Over ½ -250
Under ½ +170This one is a lock. Over all the way. Why wouldn't the TV network not want to show Mrs. Tom Brady?
What Color will the Gatorade (or liquid) be that is dumped on the Head Coach of the Winning Super Bowl Team?
Green 15/2Blue 10/1
No idea. I'll go with orange. That seems like a common flavor.
Who will the Super Bowl MVP of the Game thank first?
Does Not Thank Anyone 5/2I instantly thought God but isn't that the obvious choice? He needs to thank his teammates for making him look good. (I'm assuming it will be Brady.)
Super Bowl XLVI
New York Giants +3
New England Patriots -3
Okay, enough with the prop bets. The trendy pick is The Giants and it shows with over 60% of the bets going for them. In the last 21 Super Bowl games, Vegas has won on 19 of them. So if the majority are betting one way, do the opposite.
