MacFarlane to voice character on 'The Simpsons'
MacFarlane to voice character on 'The Simpsons'The "Family Guy" is about to join "The Simpsons," for one night only, Newsday's Verne Gay reports. Seth MacFarlane will voice a character on "The Simpsons" season finale, airing May 19. What's surprising about this appearance is that MacFarlane and the "Simpsons" creative camp have traded barbs over the years, but "Simpsons" creator Matt Groening has said the rivalry is friendly. MacFarlane's character, Ben, is described as a "charming married man who is also a swinger, and who apparently hits on Marge."
