Following the cancellation of "Roseanne" due to a racist tweet from star Roseanne Barr, Charlie Sheen has proposed a reboot of his former show "Two and a Half Men" to fill the void. Sheen, who was terminated from the show in 2011, posted on Twitter expressing his support for the cancellation of "Roseanne" and suggesting the return of "Two and a Half Men." 

Other shows, such as "Pushing Daisies," "Enlisted," and "Happy Endings," have also been mentioned for potential revivals. The controversy surrounding Barr's tweet, in which she attacked former Obama advisor Valerie Jarrett, continues to be a topic of discussion.
