Check out this new segment where we ask random people on the street so-called "Common Knowledge" questions. The answers may surprise you!

I always questioned when someone tells me, "It's Common Knowledge". How do we know what the next man knows, unless we ask him/her?

After hitting the streets of downtown Buffalo, we learn that the name Blue Ivy Carter is definitely common knowledge, along with the three branches of government.

We also discover that the Vice President of the USA, Joe Biden, is completely overshadowed by President Obama. Most people we asked never even heard of him!

Submit your "Common Knowledge" questions in the commets section, or on Twitter @JazzyTOnAir, and join us next Friday for another edition of What Do You Know?!
