The Thin White Line/Notes/Trivia

• Brian’s cousin is the same dog Peter brought home as an addition to the family in “E. Peterbus Unum. He has a larger role in the next episode, where it is revealed that his name is Jasper.
• The newspaper containing an article about Brian also features the headline “Scientists Mystified by Paper Rain,” references the paper confetti thrown on him like in most celebrations in the street.
• When Brian goes into rehab, he's put into room number 42, a number that has several meanings in pop culture. It’s possible, due to this being the first episode of the season, that this could be a small tribute to sci-fi author Douglas Adams, who died two months before this episode aired.
• The midgets posing as students in the Sunday school could be a parody of Baby Face Nelson, a short, notorious gangster.
• Gerald the Happy and Abstinent Police Clown originally sang a song that got cut for time. It was to the tune of "If You're Happy and You Know It." and the lyrics are, "If you don't have the clap, let's clap. If you don't have the clap, let's clap."
• When Brian enters Peter’s room, Peter is lying on the bed drinking from an eight-pack of beer, a notable divergence from the standard “six-pack.”
• The scene where Peter scares the woman in the pool could be seen as a parody of the commercials for the popular shark outfit pool wear.
• This episode has the first appearance of the Greased Up Deaf Guy.
• This episode is the first episode in which Stewie actually addresses Brian by his name. Unlike previously when it has either been "Dog", "Mutt" or any other Dog related name like Fido, Puddles and Patches.
• Lois knowing the exact street value of 4.5 kilos of uncut cocaine is one of many instances suggesting Lois uses drugs.
• Brian states that the real hero is God for blessing him with his drug sniffing nose, in a later episode he states that he is an atheist.
