Miss USA Nia Sanchez whiffs when asked her home state's capital

Miss USA Nia Sanchez, who might have won the title the other week thanks to a savvy answer to a difficult question, didn't do so well on Monday with a much easier one: "What's the capital of Nevada?" (That's her home state -- kind of.)

The embarrassing moment went down on "The Todd Show" on 95.5 WPLJ in New York City, and you can cringe through it here:

The correct answer? Carson City. Duh.
