Though Ethan tells Hayley and Roger he stabbed his father thirty-eight times, when they open the closet door and Ethan's dead father falls out, he is seen to have only been stabbed once in the head with a pencil. However, before the body falls to the ground, you can see his torso is bloody, obviously showing he was stabbed in the torso.
This is the second appearance of Steve's girlfriend Debbie (the chubby goth girl from "The American Dad After School Special"). It's not known why she broke up with Steve, but the two end up together again in the season four episode "Escape from Pearl Bailey".
Principal Lewis' drug name "El Lobo Negro" means "The Black Wolf."
The two magazines that Stan was offered before his vasectomy were Disobedient School Prefect and Buxom Octopus Woman.
The coffee shop is "Coughy's Coffee Shop."
Langley Falls Post front page headline: "Rumsfeld Steps Down... On Puppy's Head."
Stan: What does Steve see in Debbie? Maybe he's going to turn her into condos.
Hayley: Roger, your lecture today was just ideological nonsense.
Roger: Oh, really?! You've just earned yourself a week of detention!
Hayley: There's no detention in college.
Roger: Oh, right, well, then I'm taking away fifty points from Gryffindor!
Steve: (To Francine) You, um, you look good. Say hi to your folks for me.
Debbie: (Whispers to Steve) She looks awful.
Ethan: Professor, I was wondering if you'd like to come to dinner at my home. Hayley, you should join us, too.
Roger: Hayley, just so we're clear, you're only coming because you got caught in the gravity of my invite. I was so invited that it invited everything around it.
Hayley: Roger, how'd you come up with that lecture?
Roger: Ah, I just stitched together a little Mr. Holland, a little Dead Poets, and the rest is just lies.
Stan: A world with no children. Future generations will thank us.
Klaus: Francine, why not just replace Steve? You know, have another baby.
Francine: Stan would never go for another kid. His mind is made up.
Klaus: It's not his mind you need.
Steve: I don't have any drugs! I'm totally clean!
Principal Lewis: Do you expect me to take your word over that of an anonymous tipster?
Francine: You know, cucumbers are just brineless pickles. I could have de-brined his pickles! Who does that fatso think she is?!
Stan: Oh, is Debbie a larger woman? I hadn't noticed.
Roger: Why does nobody respect me?
Hayley: Roger, you're an uneducated alcoholic. You don't know anything except QVC return policies.
Roger: That's a specialty, yes, but I have a lot of smart opinions, and...
Stan: Can it! You're the Adam Sandler of this house, and nobody wants Punch Drunk Love. Just give us Waterboy.
Francine: It's so cute that Steve has a little girlfriend.
Stan: Well, don't tell Debbie about her because she'll eat her.
Steve: I'm so glad you came over for dinner, Debbie.
Stan: Yes, terrific to have my son's girlfriend gobbling up my family's precious food.
Debbie: Everything's so delicious. Mr. Smith, can you pass the potatoes?
Stan: Ethically, I don't think I should.
Stan: (While being swept away in a river of sperm) Ah! I feel like Tara Reid on an average Tuesday!
Francine: Why aren't these labeled? I won't know who's sperm I'm getting. It's like I'm blacked out at a frat house.
Stan: Francine, what are you doing here? This isn't home.
Roger: I can't wait to enroll here, people are finally gonna take me seriously.
Hayley: Don't they have college on your planet?
Roger: Yeah, but if you're not Asian, it's impossible to get in.

The final lines from Francine are an allusion to a scene in the film adaptation of Stephen King's The Shining.
Francine looks for Stan's sperm and finds a sperm sample for Janet Reno, who is a woman (Francine was more surprised that it was misplaced alphabetically than it being Janet Reno's sperm).
While at the C.I.A. warehouse, Stan is washed away in a stream of what he thinks is sperm, adding "I feel like Tara Reid on an average Tuesday". Francine then finds out that it was in fact milk and not sperm shortly after.
During Stan's post-vasectomy sex, he mentions a position called the "Reverse Bulldog" to Francine, adding that she needs to punch him harder. The Reverse Bulldog is commonly known as a wrestling move.
The vasectomy office is completely Japanese-themed, including an automatic high tech operating theatre, two anime mascot-like characters who guide Stan through his vasectomy, an Asian nurse and Hentai Magazines, one of which specifically references tentacle porn, a hentai staple. The anime characters (named Kichiro and Mojiro) who guide Stan through the process are based on the mascots from the 2004 Aichi World Fair.
When Roger reveals to Ethan he's not really a professor ("I wanted people to think that I'm smart, but I'm an idiot"), he says he prefers to return to his old life of watching bad television. ("Quit trying to do The Majestic and just go back to Ace Ventura".) Both The Majestic and Ace Ventura starred Jim Carrey, and Seth MacFarlane was a writer for the cartoon adaptation of Ace Ventura.
Francine tries to have sex with Stan while he's asleep, and Stan wakes up, macing Francine and calling her a succubus.
In the introduction video Stan watches at the Vasectech vasectomy clinic, one of the two on-screen characters says "Your vasectomy is about to beginning"; a phrase of Engrish.
Fall of Saigon
Stan compares Steve with the fall of Saigon. In his analogy, Francine's uterus represents Saigon and Steve's birth represents the last chopper out.
Moonlight Becomes You
In the scene where Roger is held captive, Roger sings this song by Bing Crosby.
Stan: (recognizes the tune on the radio) My Sharona!
"My Sharona" is the hit debut single of The Knack, which was released in 1979.
The Dead Poets Society
Hayley asked Roger how did he know what to say to her class. He mentioned The Dead Poets Society. That was a movie about a class full of young poets, who has a teacher that uses unusual methods to help them. Also, Hayley's crush killed his dad. That's similar to the movie, because one of the students almost did that, but instead, he killed himself.
My Best Friend's Wedding
After Stan was mace-sprayed by his wife, he accidentally switched on the TV and shouted "My Best Friend's Wedding"! My Best Friend's Wedding is a 1997 romantic comedy film directed by P. J. Hogan. It stars Julia Roberts, Cameron Diaz, Dermot Mulroney and Rupert Everett.
Roger: ...Then I'm taking away fifty points from Gryffindor.
This is an allusion to the Harry Potter series. Gryffindor is one of the houses in Hogwarts School of Witchcraft and Wizardry. Points are either awarded or deducted based on the conduct of the students.
Roger: Electric word, life. It means forever, and that's a mighty long time.
When Roger is teaching the college course, he quotes the opening to "Let's Go Crazy" from pop artist Prince's 1984 album Purple Rain.
Episode Title: Iced, Iced Baby
This episode title comes from the song, "Ice, Ice Baby," by Vanilla Ice.
