AJ talks in all capitalized letters with exclamation marks. It's irritating and grating. I quit watching him a long time ago because I couldn't stand the noise. If he IS a performance artist, his talent is seriously lacking. I like your word - bombastic. It gets old quick.
And is not a talented artist, if artist is what he is. He is a kook. A lunatic. Offensive. And a liar. His "performance" stinks.
He means he is Bill Hicks, as in an entertainer, not a journalist.
