Even though Charlie Sheen got fired from Two and a Half Men three years ago, he's still feeling some type of way about it... and yesterday, he took to his Twitter to bash his successor, Ashton Kutcher, for his work on Sheen's erstwhile show! 

The New York Daily News is reporting that the current star of Anger Management took to Twitter to start the seemingly one-sided feud, first by congratulating his former co-star Jon Cryer on the latest CBS promo for the show, then by calling Kutcher "lame." The next day, Sheen tweeted again -- this time, with another back-handed compliment: "Hey guys, relax! Read the hashtag. Oh, and Jon, by the way, I'm so sorry I insulted your sidekick. I meant REALLY LAME." 

This, of course, isn't the first time that Sheen took aim at Kutcher. His initial campaign against the former That '70s Show star started back in 2012, after Sheen told TMZ that he was "tired of pretending that [Kutcher] doesn't suck." (Granted, Kutcher never did Platoon, but then again, we don't expect Oscar-worthy performances from Kelso, now, do we?) Though Sheen followed that statement up with a Tweet saying "Dear Ashton, My Bad," it seems that Sheen is back to being pissed off at Kutcher for reasons heretofore undetermined. 

Now, according to Hollywood Take, Kutcher has taken the high road and hasn't responded to Sheen's taunts, which concluded yesterday with a Tweet from Charlie saying "hey Ashton sorry bro all good. now quit barfing on my old brilliant show. Remember Punk'd? how duz it feel? c harpThis." (OUCH!) Now, again, Kutcher isn't exactly a high-brow thespian, and compared to Sheen, he certainly leaves much to be desired. But that, too, is a function of maturity and experience -- Charlie, we will recall, has been acting since the 1980s, and comes from a showbiz family. And, certainly, when Sheen first started out, he wasn't exactly a contender for a lead role in Citizen Kane. Maybe Sheen needs to back off a little bit, and focus on his new marriage to his Porn Star du Jour.
