Tom Brady committed one of the costliest penalties in Super Bowl history -- at least as far as the MGM Grand in Las Vegas is concerned.

The quarterback of the New England Patriots drew a penalty for intentional grounding on the team's very first offensive play of the game.

Because Brady was in the end zone and Justin Tuck of the New York Giants was bearing down on him, his heave down the middle of the field was called a safety, resulting in a huge payoff for one lucky better.

The odds of a safety being the first points in the Super Bowl were 50-1 -- and one unidentified gambler cashed with a a $1,000 wager on the proposition bet.

That meant that Brady's throwaway toss amounted to a staggering payout of $50,000. Not a bad Super Bowl memory for one person.
