Hmmmm. In college, a friend of mine played a human mage named "Sylvan Shwartz". NPC's would constantly ask him "Are you Elvish, no really, not even half?" It helped that my friend did a perfect Woody Allen impression eveytime Sylvan opened his mouth...
Lately it seems every NPC name I come up with has to be a bad and/or obscure pun.
Like the famous chef Johannes Du Boueff, more commonly known by his nickname, Spring-Veal Jack [Its funny if you recall one of Jack the Rippers nicknames was Spring-heel Jack. OK, so its funny if you don't feel the need to explain why its funny].
Or the influential half-beast abstract painter who beats his wife, Brak Ton Golok. And his sometimes friend, sometimes nemesis, the lapsed Druid turned art-critic, Clement Greensward.
Or Donatello, the cleric/brothel owner who owes his success to his multifunction magic wand which contains an imprisoned demon. His name on the street is the Right Reverend Don Magic Wand. He's inspired by this barely-beliebable real life character...
