10. She's Jewish
While it's official that Melissa Rauch was brought up in a Jewish home, she very rarely talks about her beliefs in the public domain, barring a few light-hearted jibes at her upbringing: Before Season 5 of The Big Bang Theory, she told Entertainment Tonight: "I was waiting on my doorstep for the first script to arrive, like it was Christmas morning! Not that I celebrate, or anythingbut if this little Jewish girl knew what Christmas felt like, Im sure it would be very close."
And she's not the only Jewish member of the cast, with Simon Helberg (Howard), Mayim Bialik (Amy), Sarah Gilbert (Leslie), Kevin Sussman (Stuart) and director Chuck Lorre also professing to Jewish backgrounds.
