The Big Bang Theory star Mayim Bialik has shared a throwback photo featuring her character Amy Farrah Fowler and Kaley Cuoco’s Penny.

The actress popped back to the Warner Bros Television Studios last week and snapped herself in front of a painting of the two characters.

She also used her Instagram post to encourage her fans to exercise their democratic right to vote.

“Visited some old friends today at WB!” she wrote on the caption. “And yes, I’m repping my Vote mask since there’s just FOUR WEEKS until the election! FOUR WEEKS PEOPLE. Please please please register if you haven’t yet. PLEASE!?!?”

As well as the upcoming US election, one of the biggest areas of concern right now is of course the coronavirus (COVID-19) pandemic, and fellow Big Bang Theory star Jim Parsons recently spoke about how Sheldon Cooper would respond to the current situation.

“[Sheldon] was built for this. This is the moment he was waiting for,” Parsons said.

“We had an entire episode where he did a Shelbot, where he had a video screen on a remote-controlled wheelie thing, and that was when people still needed to get together in groups. He would just send that out and sit in his room. I guess he’d be fine.”
