 In the first new scene in nearly three years, at the beginning of  the fourth seasons premiere, Peter lists 29 names of FOX shows that  have been canceled after short runs in the last few years. Not only  is this a joke at how FOX cannot keep many shows around (Peter says  that Family Guy itself was canceled to make room for these "quality  shows"), but the last name mentioned, "Greg the Bunny", is a  reference to a short lived show starring Seth Green, the voice of  Chris Griffin on Family Guy. Also, "That 80s Show", another name  mentioned, ran a few episodes and was based on "That 70s Show",  which stars Mila Kunis, the voice of Meg Griffin. Also, Peter  mentions The Tick (2001)Patrick Warburton who voices Joe Swanson  played the title character.
