Notably, while speaking to USA Today, Bialik also praised the work of Big Bang supporting actor Kevin Sussman — who plays Stuart the comic shop owner — saying, "He's part of our family.

Sheldon Cooper actor Jim Parsons also cited Amy and Sheldon's relationship as a what stood out most to him.

Furthermore, he told USA Today that two of his favorite guest stars on the show were Laurie Metcalf and Christine Baranski. "I see them as actor's actors. All the years that I watched them [before Big Bang], I would identify with them as performers, as a fellow craftsman in the field," he said. "To meet them and realize that was true was overjoying. Working with them was as rewarding and interesting as I always thought it would be."

Finally, Bernadette Rostenkowski actress Melissa Rauch chose the time Bob Newhart visited as her favorite episode.

"I've been such a big stand-up comedy fan my whole life," she told USA Today. "I had a Bob Newhart record album as a kid that was my father's (and) I did stand-up before I came to [Big Bang]. I had a wonderful conversation with him about stand-up and the live audience aspect and our love for it. I will cherish that conversation always."
