The relationship between Bill Bixby and James Komack soured toward the end of the series. It is possible this is why Tom was sent "out of town" at the beginning of the episode and Norman got all of the screen time.
Starting with this episode, the opening theme song is slightly shortened. In audio, the scatting at the end is deleted, and in video, the beach scene is removed.
Eddie's library book keeps changing covers. Sometimes it says "The Christmas Bunny," yet other times it has a plain red cover.
During the restaurant scene, Brandon makes a small mistake in a line. Mr. Sato says that he is very fond of Mrs. Livingston. Brandon says the words "as her" instead of "of her" in his reply: "I bet you're not as fond as her as Dad and I are."
At the Corbetts', Joey hits Eddie repeatedly with boxing gloves, while Tom and Mrs. Livingston just look on. Finally, when Eddie runs into his dad's arms for refuge, Tom puts a stop to Joey's hitting.
At the beginning of this episode, Tom encourages Eddie to fight back. But in episode 2, Tom tells him that fighting is wrong.
Eddie hits Joey on the shoulder, yet she puts her hand over her eye as she is crying.
At the end of the dinner scene, slow-motion reveals that Joey's punch never makes contact with Eddie.
Brandon has difficulty using the chopsticks, and resorts to mostly eating with his fingers.
Brandon seems to really enjoy ordering Jodie around!Throughout the dinner scene he's obviously trying to suppress grins. After she serves him a piece of cake, however, he smiles broadly at her as he eats it.
When Tom is explaining to Eddie that he doesn't want him to be unhappy because he and Eddie can't spend all their time together, Brandon flubs his reply: "I don't - ah - (hesitation) want me to be unhappy, either."
In Episode 2, after Eddie gets in a fight over things the other children have said about his father and the teacher, Tom tells Eddie that fighting is wrong, no matter what the reason is. Yet in this episode, Tom tells Eddie that if a bully continues to hit him after Eddie tells him to stop, he should hit him back.
Eddie starts to write his running-away note in the middle of the night in his dark bedroom. Then he stops, turns on the light, and continues writing.
As Eddie is going out the door to school, Tom is trying to cheer him up by telling him about the nice report he received from his teacher. He's doing well at "sandbox" and "fingerpainting". Eddie is in 1st grade, though. Shouldn't Tom be more concerned with how Eddie's doing in reading and math?
Eddie implies Frank is a boy he just met at school, yet in Episode 2 he's shown as a student in Eddie's class.
In a scene near the end of the episode, Eddie says the word "detergent" very carefully - it was probably hard for Brandon to pronounce, especially with all those missing teeth!
Eddie (who is frequently well-dressed in little suits in the 1st season) commits a "fashion faux pas" in the first scene by wearing bright red socks with orange pants!
After Eddie comes home roughed up from a fight, he and Tom have a talk in Eddie's bedroom. Tom wants to know if the kids are giving him a hard time because Tom's taking out his teacher. "Sometimes," Eddie answers. "Like this afternoon?" Tom presses. Eddie hesitates for several seconds, starts to say "well", but apparently Brandon has forgotten his line, so Bill repeats his, probably to prompt him. This time, Eddie replies, "Yeah."
In the first scene, Eddie is explaining what made Karen throw up at school. He repeats the word "how": "She was just showing the class how - how she could spin around 100 times without getting dizzy."
Although Eddie is supposedly in 1st grade, the equipment in his classroom looks like it belongs in kindergarten: a toy piano, plastic stacking rings, and other toys.
