I don’t know, I start to hear the same things from him. I don’t find him that funny anymore. I think he just has a “repetoire” and banks off that.
He’s funniest when appearing on Leno or Letterman or some such, being interviewed and talking off the top of his head. He has me laughing every time.
His movies are just so-so, though they do show his range.
But his greatest skills are shown in normal conversations with people. That’s the amazing part....he’s just hysterical. No one can top him, not even Jonathan Winters.
