== Dumb Voice == 

 In the article, it says "Stuart is dumb voiced by series co-creator Matt Stone." Is 'dumb voicing' or 'dumb voice acting' something? If not, then what does it mean when Stuart is being 'dumb voiced' by Stone? If the person who put it in the article means that Stuart's voice sounds dumb, then this is not the way to write it down and a citation is missing.
