Melissa Rauch as Dr. Bernadette Rostenkowski-Wolowitz
It's safe to say that most of the Big Bang Theory characters don't resemble their actual actors. Melissa Rauch is one of them! She's a small, squeaky-voiced doctor who is as conservative as she is meek.
Far From Meek
In reality, Rauch is far from meek. She's also not a doctor, but that's to be expected. She doesn't dress as conservatively as her character either!
