Charlie Sheen seems to following closely Conan O’Brien’s playbook. After joining Twitter shortly after CBS pulled the plug on his show Two and a Half Men the way Conan did after he exited NBC’s The Tonight Show, Sheen may also be considering going on tour like the red-haired comedian. According to Radaronline, the reason Sheen was at the headquarters of live-event company Live Nation today was not just to be photographed perched on its roof brandishing a machete and drinking “tiger blood” but to discuss doing a live show. That is one way to sell those 50,000 Winning T-Shirts he had reportedly ordered.

Meanwhile, Sheen delivered a disturbing performance in the latest edition of his Web show Sheen’s Korner last night, looking disheveled and painfully thin, drinking and chain smoking while rambling incoherently about mosty inconsequential things.
