The Griffin family gets new neighbors in week’s episode of Family Guy “Bigfat.” The Smiths from American Dad movie into Cleveland Brown’s old house but it turns out it’s just a dream sequence of Hank Hill, which is followed by a frame by frame recreation of the King of the Hill opening.
Alternate openings have been used in several other episodes including “Whistle While Your Wife Works” in which Peter falls on a backup dancer and “Valentine’s Day in Quahog”, which parodies chick flicks.
