When is the newest Season of Two and a Half Men airing?

Cannot wait to watch more antics from Charlie sheen! It's so inspiring to know that through all the drug issues charlie has been through, he still has the time to make more episodes of Two and a Half Men. Without him, the show would be nothing, and I would never even dare watch a single episode without him in it! Anyway, how long till we get to see more of the womanizer that is Charlie Sheen?
