When Ashton Kutcher appeared on Conan on Oct. 28, Conan O’Brien asked him about Charlie Sheen’s recent comments suggesting he’d like to return to Two and a Half Men in its final season. And it’s clear in his response that there’s not much love for his sitcom predecessor.

O’Brien posed the question to Kutcher, who said he’s “stopped listening to what Charlie Sheen said.” In fact, all he hears are the trumpet-like sounds of Charlie Brown’s teacher.

“I just keep saying thank you for the great job,” Kutcher said, owing his great job to Charlie Sheen “not having it anymore.” When O’Brien pushed the question a little further, Kutcher just exclaimed “I don’t even care,” before transitioning into a clip from his show.

But, blame it on bad karma or, as Kutcher does, technical difficulties by Sheen in the booth, the clip doesn’t actually run. Instead, a behind-the-scenes error caused the clip to instantly freeze, as Kutcher and O’Brien stalled until the issue was corrected and the clip played as planned.

For Sheen’s part, the actor recently told TV Guide that he had posed the idea of returning to the sitcom’s producers. Sheen said to TV Guide that “I’ve reached out to them and they’ve reached back. We’re trying to figure out what makes the most sense.”

Earlier this year before Sheen’s comments, CBS entertainment chairman Nina Tassler said “We’re not having those conversations [about Sheen’s return] right now.”

While Sheen’s return remains up in the air, he definitely will not be returning for when Two and a Half Men premieres on Oct. 30.
