do you really think the audience really laughs at all those jokes? They don't have a laugh track machine and an applause board for nothing you know.
Why do you think they very seldom pan the audience when Leno or any of those other late night insulters do their script?
The problem isn't just the comedians, it's the writers that feed them their material as well. But the comedians are also more than willing to read it and add their style to it, which makes them full party and just as responsible for it.
Yes. I do.
The population as a whole, probably not, but Letterman fans, yes.
