Many have speculated whether "Two and a Half Men" would invite Charlie Sheen back for an appearance in the show's series finale. Sheen's latest tweet points toward no.

The 49-year-old actor tweeted a confusing series of lines that seem adapted from the CBS comedy's theme song. The short rant came on Thursday morning, according to TMZ.

Read the tweet (now deleted) below:

"men men men

men - men me suck,

gotta suk me more men before they suk me more men"

Sheen has campaigned for months to get back on "Two and a Half Men" before the series wraps on Feb. 19. CBS fired him in 2011 following his bizarre attacks against the network, Warner Bros. Studios and the show's creator, Chuck Lorre.

"I've reached out to them and they've reached back," Sheen told TV Guide Magazine on Sept. 22. "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."

His character, Charlie Harper, died at the beginning of season nine in an off-screen train accident and was cremated. Ashton Kutcher replaced him as Jon Cryer's co-star on the long-running series.

Kutcher seemed to hint in an appearance on "Ellen" last month that Sheen had already filmed a guest shot in the final episode. He admitted he was "scared" and "a little terrified" when he learned of the episode's premise, and host Ellen DeGeneres immediately followed up with the question, "Does Charlie come back?"

Kutcher found no words to answer that question except to giggle like a little schoolgirl. He did issue a warning to anyone working at Warner Bros. Studios where "Two and a Half Men" (and "Ellen") film.

"If you're working on the Warner Bros. lot, if there's sirens, come save me," Kutcher told DeGeneres.

He refused to say explicitly that Sheen would return. DeGeneres took it upon herself to predict the return of the character Charlie Harper on the CBS comedy.

Kutcher then added, "If you smell something, I wasn't smoking it."

"Two and a Half Men" will bow out on Thursday, Feb. 19 at 9 p.m. for a one-hour series finale.
