American Dad!

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.
