Halfling savage chief in Dark Sun named Meddlewhoop Nub-Nubs. Meddlewhoop lasted about one and a half sessions before he got killed by slaves, suggesting that character survival chances are inversely related to the stupidity of the character name.
I've also used the following whimsical pantheon for a couple of one shots:
Ogg - (NE Lesser Demiurge)
Domains: Evil, Healing, Air, Protection
Tquirky - (LN Greater Goddess and Giant Walking Mushroom)

Gleebus Wurp - (NG Failed Archdemon, cast out into the upper planes)
Domains: Good, Destruction, Death, Travel
Yutz - (N Mystical Divine Flying Rock With Propellors)
Domains: Magic, Water, Strength, War
Urkh Ob Glurkh - (CN Part Time Demigod)
Domains: Chaos, Earth, Trickery, Sun
