After 12 seasons, CBS's hit sitcom Two and a Half Men is coming to an end. The show, which featured stars Charlie Sheen and Jon Cryer, became a staple for the network despite production shake-ups. The news of the finale did not shock industry insiders, as the show had already gone through changes when Sheen left and was replaced by Ashton Kutcher. The one-hour final episode is scheduled to air on Thursday, February 19th.
