On the South park episode where Cartman is trying to find out who is his father for the first time, it talks about the Denver Broncos all slept with Mrs. Cartman so they didn't know who the father of Cartman is. At the end of the show, Mefesto names all the males in the room, calling the Broncos the 1989 Denver Broncos. Just before the show is "to be continued", a voice over comes in and says:"Who is Cartman's father? Could it be...." and the voice starts saying the same names as Mefesto but instead of saying the 1989 Broncos, the voice calls them the 1991 Denver Broncos. Which one is the right title?
