"I just stopped listening to things that Charlie Sheen says," the 36-year-old actor admitted on Conan O'Brien's Tuesday show. "Charlie Sheen has become like a parent on Charlie Brown to me.”

That being said, he's still grateful that he was chosen to replace Sheen after he was fired from the CBS sitcom. "I just keep saying thank you for the great job," Kutcher quipped. "I've got an awesome job and it's thanks to you not having it anymore. I'm just gonna keep going to work and collecting the check. So whatever."

At the point in the interview when O'Brien was to cut a clip from "Two and a Half Men," the footage froze instantly, which led Kutcher to joke, "Charlie Sheen is running the clip operation back there!"

Back in September, Sheen expressed interest in returning to the CBS show as it nears its series finale. "I've reached out to them and they've reached back," the 49-year-old actor, who currently stars on FX's "Anger Management," told TV Guide Magazine. "We're trying to figure out what makes the most sense. If they figure it out like I've presented it to them and they want to include me in some final send-off, I'm available and I'm showing up early. If not, it's on them."
