1) All of the player characters have catastrophically low Intelligence scores

2) The players are The Forces of Fate, trying to guide their characters into becoming the Heroes they were meant to be (while keeping the character's actions in line with said catastrophically low Intelligence scores)

3) The DM and various NPCs are making a solid effort to make the characters Hapless Goons for the Great Evil of the day

Ideal result: A campaign that should probably have Yakkity Sax playing over the entire background
