Sign in hand and questions in mind, our Courteney Jacobazzi set out to play Fourth of July trivia.

The questions started easy: How many stars are on the United States Flag?

Everyone knew that answer: 50.

----------

Next, we showed a picture of Thomas Jefferson, the man who wrote the Declaration of Independence, and asked who he was.

That one stumped a few people, but not many too her surprise.

----------

The next question may make you hungry: What is the #1 sold food on the Fourth of July?

The answer: Hot dogs

According to the National Hot Dog and Sausage Council, Americans will eat roughly 150 million hot dogs on Independence Day.

Finally, we wanted to get people singing. Courteney sang the first line of the "Star Spangled Banner" and had people fill in the rest.
