Prop bets are as much a part of Super Bowl Sunday as clever commercials and heartburn from (urp) too much salsa.
They're fun, but they can also be a little too enticing for folks who bet over their heads. The over/under on fumbles lost is 1.5. That number has been over four of the last five Super Bowls. But in the previous five, it was under every time.
Remember, folks, those casinos in Vegas aren't getting any smaller.
