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, respectively, 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 I. A more likely explanation is that being a veteran of World War II, 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. However, later flashbacks of baby Bart show that he doesn't suck on a pacifier.
Several other couples that were attending the marriage retreat with Marge and Homer were cut from this episode's script, including Edna Krabappel trying to reunite with her estranged husband named Ken Krabappel, as revealed in the audio commentary for this episode.
According to this episode's audio commentary, Mrs. Krabappel's estranged husband, Ken, was going to appear in this episode. He was supposed to be based on Dean Martin, but he somehow ended up to have a southern accent that made him sound like a hick. However, this was cut from the episode's script.
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 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.
