I'll nominate The Colour of Magic by Terry Pratchett.

Terry Pratchett has invented a phantasmagorical universe in which a blissfully naive interplanetary tourist called Two-flower joins up with a drop-out wizard whose spells only seem to work half of the time.

Together they undertake a chaotic voyage through a crazy world filled with monsters and dragons, heroes and knaves. Pratchett has taken the sword and sorcery fantasy tradition and turned it in its ear to create an entertaining and bizarre spoof.
