Melissa Rauch kept the glasses that Bernadette wore on The Big Bang Theory

After Melissa Rauch finished shooting her final scenes for "The Big Bang Theory," she went to return the glasses that her character wore for years.

"I was about to hand them back and Steve Molaro, the executive producer, said, 'I think you should have those.' I'm so glad that he did."

Rauch went on to explain that the glasses have sentimental value to her and that she came to this realization on the final day of shooting.
