Fallon is no Johnny Carson.
I have not been a fan of Fallon's. His jokes aren't knee slappers. His comments after the suspension of Kimmel showed how weak he is. I saw two live tapings of The Tonight Show With Johnny Carson hosted by Carson. (We saw a third that was guested hosted by George Carlin, who we both loved back then and saw live a couple of times.) While Carson tried to stay centered, he also knew how to hit politicians with sharp points on occasion. Fallen doesn't.
True story: This happened both times we saw the Carson tapings. You remember how Johnny used to swing an imaginary golf club as he went into the commercial after his monologue? Once the monitors in the studio went black and it wasn't going out on air, Carson would say, in his most inimitable and exaggerated Carson tone "Oooooooooooooooooh shit!" The audience screamed in surprise each time we heard it. I'll never forget that.
