Announcer: “Will our younger viewers get this Soap reference?”
“Soap” was a sitcom that aired from 1977 to 1981. The joke partly being the cast of “Soap” would stand still while a similar voice over would happen and then the family would start fighting just like the Griffins.
The other part of the joke being Family Guy using references that out date some of it's viewership by a decade or so.
