Guybrush Threepwood does not have an American accent. He just doesn't. He has a cool British accent. Case closed. The more LucasArts attempt to cut and paste the 'official' vocals of Dominic Armato over Threepwood's voicebox, the further they are straying from the vital template that exists inside my head. In the days before CD-ROM, I forged this character's voice in the more central parts of my brain, and ever since its creators have done their utmost to undermine it. The same goes for Stan the used ship/coffin salesman. Stan doesn't sound like that in my head either, and his voice should accentuate more whenever his hands point directly upwards.
