  • The only time Captain Underpants appears in the episode is in the comic and the prologue when the heroes are being interviewed about the start of Season 2.
    • Captain Underpants spoiled the story by saying he’s not in it, which leaves the interviewer, Rap Talkwell, confused.
    • This also means this is the first episode where the original Mr. Krupp did not turn into Captain Underpants.
  • This is the only episode where neither Captain Underpants nor Mr. Krupp interact with George and Harold.
  • Combining robots are a staple of series such as Transformers and Voltron, which was also mentioned by George saying, "Somebody's been watching Voltron."
  • When the Teachertron 'dies' during the class lesson (thanks to short circuiting due to a cloned input control), the other robot performing the surgery throws his arms up and wails "nooooooooooo", which is a reference to Darth Vader mourning the death of his wife Padme in Star Wars: Revenge Of The Sith
  • This is the first episode Harold and George turn Mr. Meaner into a superhero called Sergeant Boxers, replacing Captain Underpants since he's absent, this is also Sergeant Boxers' debut.
  • George and Harold are no longer expelled, thanks to the new school superintendent, Grace Wain, since this is her debut. She reveals that Jerome Horwitz Elementary isn't zoned for robot teachers.
  • Harold's statement of Captain Underpants never winning the O-Ramas was false, because Captain Underpants won an O-Rama in The Jarring Jerkiness of Judge J.O.R.T.S., being Her-O-Rama.
  • Moral: You should always help when needed.
  • The narrator doesn't say George is the kid on the left with tie and the flat top, and Harold is the kid on the right with the T shirt and the bad haircut, then "remember that now." Rap Talkwell does it for him.
