Super Bowl prop bets: How long will the National Anthem be?

There are two kinds of prop bets. One involves actual players on the field. The second is everything else.

When it comes to celebrities, they fill the majority of the bets in that second category.

A handful of prop bets revolve around National Anthem singer Alicia Keys because ... why not, right? Will she get booed? Will she omit a word? Will she add a word to the anthem?

Maybe the most interesting is this one:

How long will it take Alicia Keys to sing the US National Anthem?

Your choices are:

• Over 2 minutes, 10 seconds
• Under 2 minutes, 10 seconds

That's a tough line. The over is set at +120, while the under is set at -160.

If you want to take some action on this prop bet, consider some of the following background information.

Kelly Clarkson had the same prop bet set when she sang the National Anthem last year. Her over/under was at one minute, 34 seconds. Do you know how that bet ended?

Push.

Two years ago, Christina Aguilera had the honors of singing the National Anthem (not well, but she sang it). The over/under on the prop bet was one minute, 54 seconds. Do you know how that bet ended?

Push.

Obviously, the betting gurus in Las Vegas are really, really, really good. Or, they're magicians. One or the other. Regardless, this is really hard.

Here's what's going for you this year, though: The over/under is set at 2 minutes, 10 seconds. In the last two years, neither singer has even broken the two-minute mark. Even Aguilera, who is known to stretch out every syllable until she turns blue in the face, didn't hit two minutes.

It's a dangerous play, but we're talking Super Bowl prop bets here. They're all dangerous.
