Also in church, when Maude sees Homer looking for Marge, she hastily checks to make sure her blouse is fully buttoned. (The scene takes place the very next day after Homer looked down her dress during the party.)
Marge urges Homer to go easy on the "al-key-hol". The last time she used that term she was halfway in the bag herself, and performed similar embarrassing drunken revelry at Mr. Burns' picnic in There's No Disgrace Like Home.
Gloria and John are voiced by Julie Kavner and Dan Castellaneta, making it a rare time where they voiced a couple other than Homer and Marge. Also, Julie's role of Gloria is one of the few times she has voiced a character other than Marge or one of the women of the Bouvier family.
Grampa sings "Over There", a popular song during the First World War, when getting out of the shower, possible evidence that he served in World War One. A more likely explanation is that being a veteran of World War Two, he was a kid during the years of the First World War, and had heard it then.
A flashback sequence shows Bart sucking on a pacifier as a baby, like Maggie in the present.
When Ned Flanders is making drinks at the Simpsons's party, much of the flashy ways he is seen preparing the cocktails is similar to Tom Cruise's bartending stunts in the 1988 film Cocktail.
The music in the scene where an infant Bart chases his teenage babysitter with the car is similar to the score from The Omen.
Homer's false memory of the party is a reference to the Algonquin Round Table, a group of New York City writers, critics, actors and wits. The guests and the party and the way they are drawn resemble Al Hirschfeld's caricature of the group. As Hirschfeld's drawings were always in black and white, the color scheme is borrowed from the covers for The New Yorker.
Homer's marathon attempt at catching General Sherman, his bludgeoning of the fish and the line "I love you but I have to kill you" are all based on Santiago's fight with the marlin in Ernest Hemingway's The Old Man and the Sea.
Homer sings "We Are the Champions" by Queen after he finally catches General Sherman, although he butchers the lyrics by singing "I Am the Champions", in which he fails to singularize the lyrics in order to describe only himself.
The picture of General Sherman in the service station is a reference to the famous hoax picture of the Loch Ness Monster.
