Charlie Sheen said goodbye to his 8 million Twitter followers on Friday with the tweet: "Reach for the stars everyone. dogspeed cadre. c out." He also posted a picture of a bottle of Tabasco sauce from inside a private jet. He told TMZ he was quitting the site because he "feels like he's not getting anything out of the social network". Maybe he needed the support -- viewership of his new FX show Anger Management just dropped to 2.4 million from 3.4 million.
