Full-time bad boy Charlie Sheen has told his Two and a Half Men replacement Ashton Kutcher to "quit barfing on my old brilliant show" in a series of less than edifying twitter postings.

Sheen was fired from the hit sitcom nearly three years ago and last Sunday he bombared his replacement with tweets ranging from good-natured ribbing to some good old Sheen spleen-venting.

"hey Jon!!! u r a GENIUS!!! I effin love and MISS YOU old pal!" he wrote, adding, "Q; who's your lame side-kik? c #NiceTryCanonBoy #CH." Sheen wrote on Sunday.

After fans of Ashton's character Walden Schmidt voiced their displeasure, the Anger Management star took to Twitter again on Monday (January. 6), to explain himself. "hey relax everyone! read the hash tag! oh and Jon I'm so sorry I insulted your sidekick," he wrote, "I meant REALLY lame c."

Signing himself as Charlie Harper and including a mugshot of Woody Allen from the 1969 movie Take The Money and Run, he topped it off with the following soonafter, "hey Ashton sorry bro all good. now quit barfing on my old brilliant show. Remember Punk'd? how duz it feel? c harp."
