Chris Brown performed on Good Morning America and decided to take the opportunity to show the yet again what an unstable, violent lunatic he is.

During an interview segment, Chirs was predictably questioned about the Rihanna incident, causing him to fly into a rage, rip off his shirt and storm off set. TMZ reports:

"Brown freaked out, storming into his dressing room and screaming so loud, the people in hair and makeup became alarmed and called security. We're told Brown was out of control, and one source present tells us he smashed a window in his dressing room, and the glass shattered and some shards fell onto 43rd and Broadway."

Not surprisingly, Chris took off before security reached the scene, but not before he physically threatened a producer and reporter who work on the show. The insanity continued on Twitter where minutes later, Chris wrote, "I'm so over people bringing past shit up!!! Yet we praise Charlie Sheen and other celebs for there bullsh!t!!" Chris Brown doesn't like being asked why he's a violent psychopath, so his response is to fly into a rage and compare himself to Charlie Sheen. Makes sense to me. Stay classy, Chris!
