Book of Exalted Deeds gets yet another vote. It had such a 'must churn out antithesis of BoVD' feel, yet had none of the creativity.
But how about ALL of the Kalamar books? Kalamar has the worst spells (esp. the Villain Design Handbook...shudder), feats, and then the most pointless monstrous manual ever. My roommate bought them all for a campaign that went nowhere, and to this day I think of all the Kalamar books of being treatises on how NOT to write a gaming supplement.
