- Gimpy setting up his room so that he never has to leave. Ever.
- The Risk episode, on so many occasions:
- The guys are in a Risk game, and Rocko has been defeated, whilst Cal is so completely inept that he a) doesn't realise that Nitz and Gimpy have called a truce against him (keep in mind, when the truce was made, they openly discussed the terms in front of him, and pose for a photo op with the signed documentation) and b) he's tangled up in a sleeping bag. Meanwhile, Nitz realises the only move he can make is to attack Gimpy, so he does. Gimpy sees this as the ultimate act of betrayal, and retaliates with a kamikaze attack. Nitz then points out how stupid this move was, as Cal's forces now outnumber their forces so greatly, they have to surrender.
- The mere fact that the reason Nitz doesn't want to play Risk specifically is that Gimpy always gets beaten to the point that he starts screaming "KAMIKAZE!" and launching suicide attacks on everyone, which always results in Nitz winning.
- Gimpy calling on Mump to serve as his technical advisor over radio and watching over surveillance camera. At one point, when Mump suggests Gimpy to form an alliance with Nitz, Mump has to tell him "it was from Star Wars". Funniest of all? Gimpy believes it.
- And finally, the revelation that the festival at State U has disintegrated into a flaming warzone, all because Nitz was playing Risk, instead of being at the festival to stop one very minute thing from happening.
- Jessie keeps complaining about how Nitz is always doing everything Kimmy asks him. Also Nitz is always asking favors from Jessie. After hearing how the game works, Jessie immediately joins the game and foils Nitz's escape plan.
- Gimpy sends Mump in his place for Christmas so he doesn't have to leave his room.
"I'm out of the will, but it's worth it."
- From the first episode, when Rocko hallucinates Mump as the Great Gazoo:
Rocko: Oh Great Gazoo, what should I do?
Gazoo: Continue making a jolly old ass of yourself.
- "Good evening ladies, you want some sex in exchange for... sex?"
- The title of Rocko's self-made book: "Things Cal Does That Make Me Want To Kill Him Dead Dead Dead Dead DEAD!"
- Rocko's fake ID◊ reading "I am 21 so drinking is yes."
- Rocko tries to sell his sperm for money, and discovers they only accept sperm from people going to good schools like Techerson Tech — Gimpy's school.
Rocko: Gimpy, can I jerk off in your room?
Gimpy: (angry face) Rocko!... What do I say every time you ask me that?
- Rocko complaining that he didnt get to feel up the actress he was in an informative date rape sketch with.
- The gang attempting to find free sources of entertainment while their source of income has dried up, which ranges from sneaking into a Jewish sabbat dinner, to attending a crappy Christian rock concert.
- The clique completely falling apart while Nitz is in self imposed exile in his room as Room Guy. Without Nitz to guide them, Rocko has used negative conditioning to turn Cal into a carbon copy of himself and then descended into madness because Cal not being annoying anymore meant he didnt hate him, which went completely against his world view, Cal has turned feral and decided to live among the squirrels because his new Rocko/Cal persona means women are no longer interested in him, and Gimpy has become obsessed with obtaining Nitz's fame as Room Guy for himself.
- Nitz attempting to create a defining identity for himself to make himself notable to the other students, which consists mostly of grafting the identities of everyone else into a single personality.
- Also from "Identity Crisis", we have Gimpy's increasingly desperate attempts at luring Nitz out of his room, including sending out his sidekick, the portly Mump, dressed up as Nitz' crush Kimmy.
Mump: Oh Nitz, it's me, Kimmy Burgen, your one true love! Please come out of your room and make sweet love to me!
Nitz: No, Mump!
- From the last episode, "Screw Week", we have the incredibly crappy student housing the group comes across while looking for options of where to live next semester, such as a cardboard box without water, electricity or air which costs $3,000 a month, and a dilapidated town house with most of its ceiling missing, and a broken toilet.
- This gem from Cal about being a mascot.
This costume gives me great power. Power to install school spirit and make people cheer. But with great power comes great responsiblity. I'd be letting the school spirit down if I didn't show, and the school spirit is a ghost who will kill me if I fail. Ghosts are scary guy.
- Rocko attempting to start a sports team rivalry between State U and his own school by himself, despite the fact that his school doesn't even have a football team, and his efforts mostly consist of beating up Cal while wearing his school shirt, which everyone thinks is for a fictitious college. In the end, he crashes the State U/Techerson Tech trivia finals dressed up in a mascot costume of himself to openly challenge any college, or really tough high school, to take on his college.
- Rocko taking over the Reserve Officer In Training class after it turns out Mump of all people is the teacher, and treats it like boot camp.
Rocko: Okay Mump, I want you to describe to me in detail the worst moment of your life.
Mump: Well... this one right now is pretty bad...
- Rocko's insistence on treating college life like a college movie, much to his frat brothers' frustration, including hazing himself even though hazing has been banned on campus since the 50's, and refusing to partake in the community service aspects of a frat.
