The sixth season of Family Guy first aired on Fox from September 23, 2007, to May 4, 2008. The season included 12 episodes and was shortened due to creator Seth MacFarlane's participation in the 2007–2008 Writers Guild of America strike, which resulted in Fox airing episodes without MacFarlane doing the final work. The episode "Lois Kills Stewie" was the last episode completed before the strike. When the strike ended in February 2008, Fox had already aired three episodes without any input from MacFarlane.
