Charlie was warned several times for insulting the lead producer of "Two and a Half Men", Chuck Lorre. His actions were mainly due to his drug and alcohol abuse which eventually lead to him being kicked off the show after expressing antisemitic slurs against the show´s creator. He was almost immediately replaced by the very popular "Ashton Kutcher" - suddenly, the lead character was not "Charlie Harper" but a strange billionaire called "Walden Schmidt".
