The Big Bang Theory Cast Explains Sitcom's Popularity

The Big Bang Theory is one of the most popular shows on television, and the CBS sitcom is currently rolling through Season 8. But what makes the show such a ratings hit?

The cast of the series spoke to EW.com and offered their opinions. Check out their answers below:

Jim Parsons: "[Co-creator] Chuck [Lorre] was a musician before he was a writer, and one thing all of these shows have in common is a rhythm. These shows [perform strongly when in repeats]. You've seen them three times, but it's like a pop song-its got rhythm...He'll come in when were rehearsing and clean it up."

Simon Helberg:  "He's a barometer for the truth. Like Jim was saying about the rhythm, he has perfect pitch for the truth. You know if [we hear] Chuck laughing, you know the majority of people will also laugh."

Producer Bill Prady: "To Simon's point, Chuck genuinely enjoys the shows he's producing-and that's not always true. Some make shows that they think others will enjoy."

Melissa Rauch: "[Chuck is] the comedy whisperer."

In the "Ask Ausiello" column at TVLine, showrunner Steve Molaro addresses the possibility of Bernadette getting pregnant this year.

"Question: Any The Big Bang Theory scoop? -Alek
Ausiello: Still no bun in Bernadette's oven. At least 'not at the moment,' says exec producer Steve Molaro, who adds with a laugh, 'Bernadette already has a baby in her life, his name is Howard.'"
