pun: (pun) n. The humorous use of two words having the same
or similar sounds but different meanings, or of two different, more or
less incongruous meanings of the same word.
-- Funk & Wagnalls Standard Desk Dictionary
The form of humor that fans dote on, that they slaver over, that they indulge
in among themselves, that they slather across fanzine pages, that they
interlineate and cross-quote, that they revere and unmercifully visit on the
rest of us is...
The pun.
That most witless thalidomide bastard of True Wit. That intellectually-debased
sediment found at the lowest level of humor. That coarse-surfaced imposition
on our good offices that never produces a titter, a giggle, a chuckle
or a laugh, but which takes as a measure of its effectiveness...a groan
of pain.
--Harlan Ellison
