For the complete story on "fuck", I recommend "The F Word", by Jesse
Sheidlower and Ross MacDonald.
<http://www.amazon.com/exec/obidos/ASIN/0375706348/qid=931377107/sr=1-3/002-
3767294-4827448> It has a complete etymology of the word, and even more
fun, disabuses many common myths about its origins. Also includes a huge
compendium of uses of the word.
Nothin' but good, clean fun research here...
