To clear things up: Black himself said the first blackout was a scipted fakeout and that the blackouts were his idea...
I don't see the "WWE was an asylum" thing as a dig at his time there, it was more just about building the character and establishing that he doesn't have a firm grasp on reality and is delusional. The idea that his WWE career was entirely in his head isn't insulting WWE, it's making it clear he's mentally off-kilter.“I pitched that idea and said, ‘What if we do multiple blackouts throughout the show and insinuated the technical difficulties?’ Commentary did a great job getting that over and it came off great.”
