Not only brillantly written, but laugh-out funny without (overtly) trying to be: Fuck by Christopher Fairman (March 2006). It will be interesting to see which journal, if any, will publish this. Not to mention, who will debate him?
On a side note, I missed a reference to Bill Bryson’s brilliant discussion of fuck in Mother Tongue, where he lays out all the various ways the word can be used. Brilliant, indeed.
