With the NFL's Big Game closing in, it's amazing how much money is generated by one Sunday in February.  And I'm not even speculating about the wagering that will go into the day of fun.  You can gamble on just about anything: the coin flip (heads or tails, 50 % odds you'll be right), how many points the Ravens and 49ers will combine to score (currently set at 48), how long it will take for Alicia Keys to sing the national anthem (2 min. 12 secs., last year Kelly Clarkson did it in 1:34), even silly bets like how many times Raven player Ray Lewis mentions God or Lord (3), what color the Gatorade will be when poured on the winning coach (current favorite is "clear") and even if Beyonce's hair will be curly or straight!  There is something for everyone to bet on, including of course the office pools and supersized squares at neighborhood bars and restaurants.  Here are some more hefty numbers associated with Sunday's action:

$3.8 million = average cost of a 30-second TV commercial on CBS during the game.

53 = numbers of commercial spots that have been sold.

$262.5 million = revenue from last year's TV ads during the game.

111.3 million = number of viewers for last year's broadcast (ironically more watched Madonna's halftime show than the actual game).

Alicia Keys performs the anthem and Beyonce is the haltime entertainment with rumored help from her former fellow members of Destiny's Child.  After the big hulabaloo from Beyonce's lip synched version of the national anthem at last week's Inauguration, I wonder what the odds are that Beyonce will do the entire halftime show live?
