I chose that the two option, as I love both Family Guy and American Dad. Family Guy started off strong, and the first 3 seasons were awesome, then went on a slow decline til a truly terrible last season(though 420 was a very good ep). Thankfully, this year it seems as if McFarlane and the staff are actually trying to be actually funny and improve the episodes, and I have enjoyed every one this season. American Dad started off poor, but the fact that there is actually a plot is a plus, and it has just gotten better and better(the reverse of Family Guy). Best episode of Family Guy is the Stewie kills Lois/Lois kills Stewie 2 parter. Best American Dad episode is Tearjerker.
