He just couldn't help himself, could he.

Dave posted an article yesterday featuring Ashton Kutcher giving Charlie Sheen what for on Jimmy Kimmel (he told him in no uncertain terms to "shut the f*ck up... it's been three years"), and it was only a matter of hours before Sheen managed to formulate a response. Here 'tis.

At first, he seemed understanding, even going so far as to apologise for his bitter attitude.

He tweeted: "Ashton, message received. so sorry, u sounded like me! well done! my bad I was pissed at other crap & took it out on you. hope u r good xox c. (sic)"

Then he goes batsh*t bananas saying he's going to put Kutcher in hospital: "'but news flash Dood, you ever tell me to shut the F*** up, EVER again, and I'll put you on a hospital food diet for a year. c #YaFeelMe Jr?"

Male menopause much?

Charlie regularly sends Ashton public messages on Twitter, calling him "lame."

Praising his former co-star Jon Cryer in a series of tweets last year, he wrote: "hey Jon!!! u r a GENIUS!!! I effin love and MISS YOU old pal! Q; who's your lame side-kik? c #NiceTryCanonBoy #CH (sic)"

He later added: "hey relax everyone! read the hash tag! oh and Jon I'm so sorry I insulted your sidekik I meant REALLY lame c (sic)"
