But Johnny Carson was right when he said that he could play straight man to Jimmy's comedian and wiseass who is never serious. Johnny could feed him all of the material that Jimmy would need to comment on and Jimmy without a script could do standup off the top of his head without preparation and sound hysterical. As we saw in this video with Johnny asking Jimmy basic questions about what is going on in his life and Jimmy playing comedian in response. Like saying his New Years resolution was to talk faster. One reason he is famous is for talking slow.
Mr. Smith Goes to Washington is one of my favorite movies of all-time. And even though I don't think it was supposed to be, it is also one of the funniest movies of all-time. The humor you see from Jeff Smith in the movie played by Jimmy Stewart is very similar to the real life Stewart. Observational, off the cuff, what are you thinking, no time to prepare, instant humorous analysis of what you are seeing. Which is Jimmy Stewart and what you see in this video on Carson.
