Super Bowl Prop Bet Options

Bill Barnwell lays out some of the available bets on the Super Bowl, including the "Will there be a safety" bet he blew last year.  Here's my favorite:

Will the 49ers score exactly four points?
Yes: +9999
No team in football history, to my knowledge, has scored exactly four points in one NFL game. There's only one way to get there, and it requires scoring two safeties without producing even one additional point the rest of the way. The Falcons were only one additional safety away from doing this to the Giants in the playoffs last year! I don't know what the true odds for this one should be, but you can probably add another nine to the end of that line and still be safe.

Seriously, who's going to bet on that?
