It's been on the air for a decade, and "Two and a Half Men" is still one of the most popular sitcoms on television.

The CBS ratings behemoth returns Thursday for its tenth season premiere at 8:30 p.m. Eastern Time. Though this season will see the show break the 200-episode mark, executive producer Jim Patterson said the series was completely reinvigorated with last season's addition of Ashton Kutcher in place of Charlie Sheen.

"Last year, we were scared to death because it was like, oh my god, Charlie was gone. What are we going to do?" Patterson said. "Now, looking forward, it's like this is a whole new show again. This is great."

Even so, it is a challenge for the writers to keep things fresh after a series has been on the air for so long.

"The 10th year of a show, you're looking at 225 episodes," Patterson said. "Obviously, the more episodes you do, the more of a struggle it is to go, 'All right, what's a new idea? What's something fresh we can do with a character?' "

One stunt "Two and a Half Men" is pulling to keep viewership high is bringing in Miley Cyrus for a guest role as a love interest for Jake, the character played by Angus T. Jones.

"We were so excited to get Miley. If it works out, it's going to be great. She's on for two episodes right now and if things turn out well and she has fun, we'd love to have her back. ... We think it's going to be a great dynamic," Patternson said. She'll play a romantic interest for Jake, and he's never really had that. This is going to be his first real relationship kind of thing. He's no longer the half man on the show. He's in the Army, gonna have a girlfriend, experience love and heartbreak and all that kind of stuff."

But things get tricky when Cyrus' character also develops feelings for Kutcher's character. CLICK HERE to check out a photo of Cyrus and Kutcher in bed together in a still from the show.

This season, "Two and a Half Men" moves to a new night with a new lead-in. The show will now air on Thursdays after "The Big Bang Theory."
