When Marge throws a dinner party, Homer gets drunk and makes a fool of himself (even going as far as tricking Maude Flanders into digging for nuts so he can ogle her cleavage) and Marge forces Homer to explain to Bart what he did and go on a marriage retreat (which Homer wants to abandon so he can go after a legendary catfish). Meanwhile, after their regular babysitter freaks out over memories of Bart trying to run her over with the family car, Grampa Simpson steps in to care for the kids -- and Bart and Lisa take advantage of the old man by making him do whatever they want (eat ice cream instead of dinner, smoke cigars, drink coffee, and have a wild party).
* FirstAppearance: This is the first episode featuring Snake Jailbird (the convict who always robs the Kwik-E-Mart). In commemoration, Snake's jail number is this episode's production code (7F20), though some episodes depict this as [=TF20=] due to [[OffModel bad animation/artwork]].
* FlyInTheSoup: Homer puts a fake icecube with a fly inside on Dr. Hibbert's drink. Hibbert lectures Homer on the dangerous chemicals in the plastic cube, noting that a ''real'' fly would have been safer.
* OminousLatinChanting: During the baby sitter's flashback of baby Bart nearly running her over.
