I guess this makes sense, his comedy IS entirely observational in nature. Se identifies, Ni twists.
I think this thread demonstrates just how far off the common MBTI understanding of temperaments is.
The common MBTI classification of S's is really that of SJ's. It may be because SP creativity is read into too much by N's, especially NF's. But we SPs do it for no other reason than that it's amusing to us, not because we're seeing some kind of underlying meaning or connection. Puns are puns, slogans are catchy and logos just look nice. Trying to find underlying abstraction in all of that just makes our heads hurt.
I don't see Hedberg as abstract in any way, shape or form. In fact he seems to very obviously be a creative SP. Especially since his jokes seem to distort meaning, not shed light on it.
We SPs make the best comedians, btw. And yes, the introverted SP types can get nervous onstage, at least and especially ISFPs, even though as a whole we are the boldest temperament.
Oh, and Letterman an ENTJ? Seriously?
