I'm not going to argue on this one, but you'll find quite a few of the production staff slipped into episodes. (Such as Goodman and even Seth) I pull their screenshot once they are identified to add to their pages but it's a mixed bag on including them in the character list. I don't include them unless I'm 100% positive it's them. On that note, Dominic MAY have also been in Dark Side but since I already had a good picture never bothered to pull another. --Buckimion 21:51, January 3, 2011 (UTC)
I saw the Goodman and the MacFarlane (already on the pages). I sorta expect this in projects (Stan Lee in Spider-Man 2), and it's especially expected in comedies like Family Guy--Jack's Posse Fic 21:58, January 3, 2011 (UTC)
