It is always a good idea to quit while one's ahead, and this is exactly what "The Big Bang Theory" showrunner Steve Molaro wants to do with the show.

When The Hollywood Reporter asked him if they will be treating season 10 as if it's the last season for the popular CBS sitcom, Molaro answered affirmative.

"I think so. I can't speak to the future or on behalf of the cast or where we'll be then but it's certainly possible that it could go past that," he said. "The reality is that maybe season 10 is the ending point. The real answer is I don't know and all I can do right now is go episode to episode and try to make each one the best that we can. There's still so many episodes to go. Even if hypothetically season 10 was the end, I wouldn't be focusing on that yet. That seems like something that would be dealt with way down the line."

But co-creator Chuck Lorre believes they have many more seasons left ahead for "The Big Bang Theory," since a lot of people still want to see Sheldon, Leonard, Penny, Howard, Raj, Bernadette, and Amy's stories unfold.

"I never imagined nine (seasons) and here we are," said Lorre. "I'm not going to presume to know how many years this has because it's ridiculous for me to guess. It's already gone beyond my wildest dreams so anything beyond this... as long as everybody is having a good time and we're making a show we're proud of... then it's worth continuing."

Lorre said that Leonard and Sheldon's scientific breakthrough still need to materialize before the show wraps up. He believes that the two scientists deserve their time in the spotlight simply because of their deep love for science.

"I'm still fascinated with how their work might impact their personal lives and seeing how progress in their work can change their characters, relationships and themselves," he said. "I'm always intrigued with these guys who have chosen a life of where they're not money motivated; they're not entrepreneurs or looking to get rich; they're looking to unravel the secrets of the universe. I find that fascinating and I like that they're not on the money train but have a very personal mission to learn about the world they live in. I hope we do more of that."

At the same time, Molaro said that they have so many character stories that have not been tapped.

"There are things floating around that we talk about and say, 'Someday, that might happen,'" he said. "There are still a lot of characters out there in this world that we've never met that I'm still excited, over the next season and a half, to get a chance to do something about. We've never met Penny's mom, Leonard's dad, Sheldon's Meemaw or Howard's dad - and that's a big tentpole that's still floating out there."
