Charlie Sheen returned to CBS on Monday night -- and once again trashed "Two and a Half Men," the show he once starred in for the network.

Sheen -- who was shown the door at the hit sitcom in 2011, after a litany of bizarre behavior -- dropped in at CBS's "Late Show With David Letterman" for a wide-ranging chat that included a dig at his former show.

The exchange actually started out on a pleasant note, with Sheen -- who currently stars in the FX comedy "Anger Management," which returns for a second season on Thursday -- noting that he'd like to appear on the series finale of "Men."

Reminded by host David Letterman that his character, Charlie Harper, had been killed off, Sheen quipped, "I am dead, but so's the show."

Oomph.

Sheen went on to allow that the show's cast and crew are "doing the best they can," but predicted, "I think they have one more season."

The actor also reflected on his former co-star Angus T. Jones' recent controversy, when he characterized "Two and a Half Men" as "filth" and urged viewers not to watch it in a YouTube video. While Sheen said that he had not had a chance to talk to Jones about it, he opined that the video fell short of his own highly public blow-up.

"That's not Adonis DNA, no; not even close," Sheen said, referencing a catchphrase from his own freakout.
