I have been remiss:
When mentioning
Fafhrd and the Gray Mouser and their roguish ways and happy shenanigans - with evil wizards and willing 'maidens' (one may interpret that word in many different ways

) - then one
MUST include
Cugel The Clever, by
Jack Vance.
(Available in the Vance Integral Edition or the old Ace edition.)
And then there is
Nift The Lean, by
Michael Shea - but that's another post.
