In "Straight Up Juggahos", the boys scheme to set Jillian up on a blind date with a man they found online, telling her he is a friend named Jake Heisenripbauer (a name they made up on the spot). At the very end of the episode, Jillian calls him by the said name, leaving us to assume that she's been calling him that the entire time and that she still doesn't know his real name.
"Model Kombat" has Blake meeting a sports shop owner who lost nearly all his sight during the war when a piece of shrapnel hit him, but Blake mistakes his words for "pizza shrapnel." Later in the episode, Adam throws a pizza slice at Ders. Blake immediately yells at him, asking if they have any idea how many people go blind due to pizza shrapnel.
In the cold open of "In the Line of Getting Fired", Adam says that he'd be willing to give head to a man for $900 (which he immediately recants). During the closing scene, Blake is being put into an ambulance after being shot and asks how much it will cost him since he doesn't have insurance. The paramedic says $900. Blake and Ders then tell Adam to put his money where his mouth is.
Continuity Nod: Jillian mentions her cat Brent Hoffman dying in the season two episode "Man Trip". In "Fat Cuz" she tells Adam's fellow cat-loving cousin that it is the anniversary of Brent Hoffman's death.
The Danza: The three main characters are all named after their respective actors. Also, Jillian.
Depending on the Writer: The boys' level of immaturity, Jillian's intelligence, Alice's hostility, etc. often fluctuates between episodes.
Don't Explain the Joke: When the boys pull a "Poop Dollar" prank on someone (they wrap a dollar around poop and then leave it on the ground for someone to pick up or step on), one of them shouts "See we poop in the dollar!" as the victim runs away. When it happens again, they all yell "POOP DOLLAR" as they drive away.
Jerk with a Heart of Gold: Alice is indeed a verbally abusive Bad Boss, and in the episode "Model Kombat" she outright tells Adam that she wouldn't care if he died. Later that episode, she doesn't hesitate to save him from choking to death, and afterwards she even grudgingly lets him hug her for a second.
Karma Houdini: The high school kids who crash the boys' home and party, along with decapitating their beloved dragon statue.
The guys address this in the commentary, stating it was by far the least popular ending of an episode to date.
Leeroy Jenkins: Adam pulls a Leeroy out of his shroom fueled haze in the first season episode "Office Campout", ruining Blake and Ders' ridiculously childish plan and running straight at who he thinks are burglars, but turn out to just be the tech guys coming into the office to do routine maintenance
Shown Their Work: It's unknown if there are any actual Insane Clown Posse fans on the production staff, but they go surprisingly in-depth into the Juggalo subculture for the episode "Straight Up Juggahos", right down to having one of the Juggalettes dub Adam "Sugar Bear" (the name of Shaggy 2 Dope's character in Big Money Hustlas) in one scene. Sure, they spend most of the episode mockingJuggalos, but at least they got the details right.
The Slacker: Blake, Adam, (and Anders to a lesser extent).
