Summary: After Emily fails a test, the twins wonder whether school is the best way to learn—prompting Grandma to whisk them off to a familiar place in the past, before stopping by the most famous mind in history, and then a rumble in the jungle...
This episode contains the following tropes:
- An Aesop: "Classrooms aren't required when learning is desired."
- Attention Deficit... Ooh, Shiny!: A tiger student is instructed to climb a tree for a test, but he can't focus on it and instead chases a butterfly.
- Been There, Shaped History: Gabby and the twins zip past Einstein's desk, causing him to glance up from his work in surprise with his tongue sticking out—right as a photographer snaps what is arguably the most famous photo of him.
- Cliffhanger: At the end of the episode, someone kidnaps Derek. Was it Karinne...or something else?
- Furry Reminder: After finally making it through the tree climbing test, the tiger cub decides he's hungry, and the other animals look delicious.
- Given Name Reveal: We learn that Mrs. Tuttle's first name is Julia.
- Historical Domain Character: Albert Einstein makes an appearance, much to Emily's delight.
- The Knights Who Say "Squee!": Emily is beyond thrilled to meet her hero, Albert Einstein.
- Literal Metaphor: Gabby takes the twins to a literal jungle to demonstrate a literal version of the "don't judge a fish by its ability to climb a tree" parable.
- Never Heard That One Before: When Einstein asks Gabby how she's been, she responds, "Relatively good!" Einstein gives a forced chuckle at that and whispers to the twins that that joke gets old fast.
- Parody: Phil Gerson the Science Person is a clear parody of both Bill Nye the Science Guy and Neil deGrasse Tyson.
- Sarcasm Mode: The koala teacher sarcastically quips that he doesn't mind letting two random strangers waltz into his classroom and start teaching. The twins take it as permission.
- Self-Parody: Amanda Lee (Kevin's mom) is an animator and created a cartoon called "The Quiplet Triplets."
- Shout-Out:
- Shown Their Work: The koala teacher has two thumbs, just like real koalas.
- Toilet Humor: Karinne is given a new weapon for capturing Derek by F.A.R.T. The descriptions Larry makes of it are full of flatulence jokes.
