American Dad! (season 5)

American Dad!'s fifth season originally aired on the Fox network from September 28, 2008, to May 27, 2009. It consisted of twenty episodes and was released as two DVD box sets and in syndication. American Dad! follows the dysfunctional Smith family—father Stan, mother Francine, daughter Hayley, son Steve, the pet fish Klaus, and extraterrestrial alien Roger, all of whom reside in their hometown of Langley Falls, Virginia. Season 5, which premiered with the episode "1600 Candles" and ended with "Stan's Night Out", was executive produced by David Zuckerman, Kenny Schwartz, Rick Wiener, Richard Appel, Matt Weitzman, Mike Barker, and series creator Seth MacFarlane. Weitzman and Barker served as the season's showrunners.

Season 5 satirized various political and social topics, including incest, the coming out aspect of homosexuality, and appeal to fear propaganda. The season was met with generally positive reception from critics. Some went on to criticize the show for the level of inconsistency. However, the over-all development of the show during this season was praised by critics, saying that "the show has grown into its own over the past seasons." The season premiere was nominated for a Primetime Emmy Award for Outstanding Animated Program (for Programming Less Than One Hour) in 2009.
