I just caught one of these -- really funny.  A few others I love (not from fishing, either looted or pickpocketed):

A frayed knot
A pound of flesh
A steamy romance novel (especially when you read it, something like, "Oh darling, I love yor long sword, blah blah blah..." and then, "This goes on for several hundred more pages without advancing the plot."  XD  Pickpocketed from a blood elf.
