- Second appearance of Teddy Truman, after his cameo in "Docu-Trauma".
- Teddy Truman's name is a parody on Harry Truman and Theodore "Teddy" Roosevelt.
- With the addition of Teddy, Charles Darwin Middle School officially becomes "overcrowded", in the eyes of the law, giving them emergency funding from the state.
- An anthropomorphism joke is made, when Mr. Hornbill asks the students to cross their fingers, which none of them can do, since they have either paws, hooves, fins, etc.
- "The School of Hard Knocks" is not actually a school, nor is it a pun on an existing school. It's an idiom, meaning one has gone through a painful or unpleasant experience, but has learned something important in the process. So, "Learning something from the School of Hard Knocks" has the same meaning as "Learning Something the Hard Way".
- The animals at CDMS are incapable of discriminating puppets from living creatures, due to them being nursed by humans, manipulating animal-like hand puppets to serve as their parental figures at birth.
- A flashback shows Jake as a baby for the first time.
- Said flashback shows a sock puppet, having to substitute as Jake's mother, meaning that something must have happened to his real mother, in order for her not to be there at the time. However, in future episodes ("Meet the Spidermonkeys", "Lonely Lyon", "Where in the World Are Adam's Parents?", and "Animal School Musical") and even in a previous episode ("Have Yourself a Joyful Little Animas"), it's been made very clear that Jake still lives with his true biological mother.
- Slips, Jake, and Ingrid apparently don't know what puppets are.
- Adam managed to enroll his own hand as an official student at the school by making the "Blah-Blah" hand gesture, doing a funny voice, and putting on a persona of the name "Stupid Hand". Everyone mistook this hand for a separate living being, and made it into another student at the school.
- Windsor's house is seen for the first time, through a flashback of him growing attached to Teddy Truman.
- During said flashback, Windsor and Teddy make do a reenactment of Abbot and Costello's famous "Who's on First Base?" routine.
- Fourth episode, with Adam and Jake in gym together, after "Chew on This", "Guano in 60 Seconds", "Le Switcheroo".
- Adam and Jake are seen in gym class together, but they're on separate teams, meaning in this episode, Adam's gym partner is not a monkey.
- In gym class, the students play a game called, "Ultimate Fetch", which is basically Ultimate Football, only with a stick. The stick is also tossed by the referee, as opposed to the traditional "coin toss" beginning of American Football.
- The episode's final billboard gag "Bye Bye Teddy", is possibly a reference to the movie "Bye Bye Birdie".
- It's revealed that sometime after Adam transferred to CDMS, another new student dropped in, unbeknownst to him. This student was some kind of rodent, who apparently died for unknown reasons, giving off quite an unpleasant memory to the students who knew him.
- Billboard Gag: "Cage-Free Learning" and "Bye Bye Teddy".
- Credits Gag: A bus driver drives Teddy Truman to his new school, fearing him at the same time. At the end, the driver screams and goes off course. Teddy then climbs up from over the edge and talks, proving to be well alive and self aware.
- Running Gag: Principal Pixiefrog and the students call Teddy Truman better than the last new kid (Adam, until final minutes of the episode).
