Family Guy - Episode 18 - Season 4
Family Guy's fourth season aired on Fox from May 1, 2005, to May 21, 2006, and consisted of thirty episodes, making it the longest season to date. The first half of the season is included within the volume 3 DVD box set, which was released on November 29, 2005, and the second half is included within the volume 4 DVD box set, which was released on November 14, 2006. Volume 4 was split into seasons 4 and 5 in regions outside the United States, leading to confusion over season numbers between U.S., Australian, and UK consumers. The last three episodes of season 4 were the basis for the movie known as Stewie Griffin: The Untold Story, and are edited for content; Fox does not include these episodes in the official episode count.
