The funnier, more clever, and original alternative to Family Guy. About a conservative CIA agent dealing with Suburban life as well as his family, plus he has a alien for a best friend. The jokes are better, the satire is good, the plots make sense, and the characters are more developed. Basically proof that you don't need pointless long gags/flashbacks, a gay baby, and a obnoxious fat guy to make people laugh. Plus the show gets way less preachy than family guy as the seasons go on.
If you want to compare anything to the Simpsons, use this show, because it has something family guy will never have: originality.
FG fan: Dude have you seen Family Guy last night?
AD fan: No, I stopped watching that stupid show since I started watching American Dad! and realized how much Family Guy actually is not funny..
