Feeling Great Quotes (page 3)
Great short stories and great jokes have a lot in common. Both depend on what communication-theorists sometimes call “exformation,” which is a certain quantity of vital information removed from but evoked by a communication in such a way as to cause a kind of explosion of associative connections within the recipient. This is probably why the effect of both short stories and jokes often feels sudden and percussive, like the venting of a long-stuck valve.
David Foster Wallace
