"We were on set every day. It was so exciting to watch Simon and the cast sing it. Simon is such an amazing actor and musician; he never failed to bring us to tears."

Simon Helberg is often mentioned during the show's most memorable moments. However, the actor has his own list of great sequences to take place on the show. Among his favorites, including scenes along his on-screen partner Melissa Rauch.

He also had a huge appreciation for getting to work alongside Stephen Hawking, "I don't have a quick answer for that (speaking about his favorite moment on TBBT).
