The good-hearted, ill-tempered host of a late-night talk show that takes risks that often result in laughter with the exception of "Will It Float?". The show is kept fresh by new additions such as "Great Moments in Presidential Speeches" in addition to the traditional segments such as "Ask the Audience" and bizarre contests hosted by Rupert at the deli next door. Dave has outstanding taste in bringing back exceptional musical guests and comedians such as Jim Gaffigan (13 times), Brian Regan (19 times), and the late great Mitch Hedberg (10 times). Often trails a show in ratings on NBC at the same time-slot hosted by a comedian going through the motions riding the popularity of the show's past with painfully unoriginal material.
"David Letterman seems like such a curmudgeon, but did you see how teary-eyed he got when he introduced the doctors and nurses who saved his life?"

the passive-agressive act of dramatically apologizing not only for an action which one has committed, but also for things which one has previously committed, has not committed, and would not likely commit, all in an effort to reduce one's culpability for the central action in question. This is similar to a strategy employed by jewish grandmothers, where one apologizes for all things that have ever happened, whether good or bad.
Example of a "Letterman apology":

Dave: ... so my apologies to subjecting them to that vulnerability and being brow-beaten and humiliated, it never occured to me, and as a matter of fact Alan Coulter kept wanting to know if we'd had sex, do you remember that Alan?

Alan: I did and I don't remember.

Dave: So I'll just say I'm terribly sorry ... And now, also because what can it hurt, once again I'd like to apologize to the former governor of Alaska, Sarah Palin...
