When Darrin (as a mule) is standing in the kitchen doorway, the close-up shots make it look like the fridge is on the left side of him. It should be on the right.
When the kitchen door opens, the brick wall shows. The first time, shadows of limbs show on the wall. The second time, the limbs themselves show.
When Maurice arrives, there is the usual chest in front of the living room windows. Later it is gone.
In this episode, we learn that not all of Samantha's family is opposed to her marriage to Darrin. In fact, Uncle Arthur is the one of the few members of Sam's family to call Darrin by his correct name.
Arthur puts a nut-covered banana in the tray. When Serena passes him the second one, there are three bananas in the tray.
During the skywriting scene, Samantha's hairdo and makeup change drastically.
The kitchen set used by Darrin's parents in this episode happens to be the same one used by the Kravitzes in "Weep No More My Willow".
The face of Melody Thomas, who was Elizabeth Montgomery's stand-in, is twice seen while performing with Montgomery as Serena and Samantha.
When Serena pours wine on Franklin, his hair is down over his eyes. In the next shot, his hair is neat and out of his face.
Serena tells Phyllis that she is a cousin from Samanatha's father's side.
Samantha picked up Mrs. Stephens, the cat, only to have the cat in the basket in the next shot.
At the end, Endora's spots show just before the glass passes over her face.
A brick wall shows through the wide open kitchen door, even though it should be a view of the driveway.
When Samantha pops out, an extra in the background all of a sudden appears a few ahead of where she was walking.
When Samantha gets an "air" mail from Endora, in the form of an arrow striking her wall, the message reads: "Tell your chivalrous husband that his Mother-in-law is regrettably unavailable." After she reads this, and makes a remark, the note changes to: "Guess who made me that way." The camera then goes into a long shot showing Samantha holding the note. The note is partially transparent and you can clearly tell the note has not changed. It is still on the first message.
The kitchen set used by the Kravitzes in this episode is later used by Darrin's parents in "Tabitha's Weekend".
There is no telephone at the beginning of the show. When Samantha needs to answer it, there is one on the TV. Later, the phone is on the coffee table until Larry comes and sits on the table, then the phone is gone. In later scenes, the phone is on the table again.
In soundstage shots, Samantha is wearing her necklace, but in ranch exterior shots, she is not.
Sam tells Darrin of chaos at Tabitha's school and mixes him a progressively stronger drink until he finally tells her to finish the story after he passes out. The same gag is used in "Samantha's Better Halves" when Sam tries to explain how Darrin was zapped back and forth to Japan, and also in "School Days, School Daze".
This is the only episode where Diane Murphy plays Tabitha on her own.
