All my memories of Sheen go back to Men At Work, Ferris Bueller and Hot Shots Part Deux. I wasn't even aware he was still acting. But he's HUGE apparently, enough so to justify AJ calling this "the biggest thing he's ever done". The funny thing about that is AJ has just given himself a huge insult regarding everything he's done in the past.
Reading Sheen's interview was like reading an awkward, self-aggrandizing movie script. Obama, despite his objections, being a big fan of Charlie's show and impressed by how prepared, organized and focused he is.
Apologists are saying the deception was worth it, because it created hype raising awareness about false-flag-terrorism and "it worked". Hilariously though, the few news stories it resulted in have not confused it for anything other than a fake interview. So the hoax/deception had no effect other than confusing AJ's own fans. I see no reason the story wouldn't have gotten about the same amount of attention with the disclaimer on the top right away.
