In the U.S., we celebrate Flag Day on Thursday, June 14. So in this week’s YouTube video, I’m going to teach you about flags in anticipation of the holiday. That’s right, it’s my own version of Fun With Flags! I asked for your questions on Facebook about filming the Fun With Flags segments on The Big Bang Theory and today I’m answering those questions to the best of my ability.

Let me know in the comments below if you have any additional questions—or your thoughts on flags!

And happy Flag Day!
