You and me both. His current role has been the longest he's stayed with any. He usually leaves a show complaining it isn't worthy of him.
I think that he leaves his shows because people eventually begin to figure out he’s a formulaic BS artist that doesn’t really know sh!t except how to ‘play’ an expert for gullible people. Same technique, same mannerisms and very tiresome one-shot repertoire if you watch him closely.
