I’m surprised a news program late at night did better with younger people than a typical late night talk show.
Well, at Jimmy Kimmel can’t complain he doesn’t have a good lead in show.
Shut your face AniMatsuri. Just because YOU don’t like Conan doesn’t mean millions of other don’t.
I wonder how the Letterman apologists are going to spin this one.
Oh wait, did you say KIMMEL and not FALLON?
Oh aren’t I the one who needs to shut her face.
Sorry AniMatsuri my bad. I’m just so used to people here bashing Conan.
I will proceed to dunk my head in a toilet now.

There is nothing surprising about this, Letterman is just an old hater who hides behind comedy to push his political slant, young people are turned off by that, its time for the old hate monger to hang it up
And Nightline is doing this well without it’s long-time sex symbol, Ted Koppel…
…who started Nightline thirty years ago, because of a country named Iran…
…and I am getting used to Conan now – he’s no Carson, but he’s no Letterman, either…
…if he’s himself, and doesn’t recycle jokes as blatantly obviously as Leno does, and goes “vroom! vroom! party starter!” once in a while (Bud Light – you can buy lots of ads on the top late night talk show in the demo – you owe Conan big time!), I might even like him better than I do Doc Sevrinsen’s tailor (or, for that matter, Gene Rayburn’s tailor!)
