A flashback shows Peter getting “another dog” who honks a bicycle horn whenever he wants a treat. The dog is shown again in a cutaway scene of him at Club Med on “The Thin White Line” and is revealed to be Brian’s cousin Jasper who would later acquire a pink top which is a pale green here in “Brian Does Hollywood.”
One of the students asks “So, like, can the family understand the baby or what’s the deal with that?”, reflecting a long-running controversy.
During Peter’s mindless ramblings, he mentions breakfast cereal Special K, actress Kaye Ballard and the dabbling duck-breed the mallard.
When Peter receives his notice from the IRS, he mistakes the word audit for the German automobile maker Audi.
At the IRS audit, Peter yelps over the recent cancellation of the FOX drama Party of Five, but forgets about the show the next minute. In “Stuck Together, Torn Apart”, Peter dates Party of Five co-star Jennifer Love Hewitt and mistakes the show for a pornographic film.
When Peter digs in the backyard, Stewie warns him that he may find “a human skeleton with a Lincoln log,” a wooden toy, “jammed in the temple.”
Mayor West invited civil rights leader Jesse Jackson to open the negotiations with a prayer. However, he could not be there, so West settled for La Toya Jackson, singer and sister of Michael Jackson. Neither siblings are related to Jesse Jackson.
When Stewie uses newspapers as diapers, he gladly defiles the comic strip The Family Circus, mentioning Jeffy, a character in that strip.
Peter holds a pool party for leaders of nations who congratulated him on Petoria’s “invasion” of the US.
At the pool party, then-current President of Serbia Slobodan Milošević jokes that his cole slaw is “made out of people,” a reference to the film Soylent Green.
The then-current Iraqi leader Saddam Hussein talks with then-current Libyan president Muammar al-Gaddafi at the pool party about “The Junior Mint” episode of Seinfeld; the one where Jerry thinks his girlfriend’s name is Mulva because the only clue about her name she gives is that it rhymes with a body part found on a woman.
Peter’s pool party is also attended by then-current Cuban president Fidel Castro, Panamanian General Manuel Noriega, despite the fact that Noriega had been in a Miami prison for drug smuggling for more than seven years at the time this episode originally aired. Some famous leaders who are now dead attend the party including Slobodan Milošević, who died in 2006 but was alive when the episode was made, likewise North Korean President Kim Jong-il who died in 2011, and Saddam Hussein, who was hanged in 2006 who was also alive when the episode was made, as well as black Ugandan dictator Idi Amin, who was deposed in 1979 and died in 2003. Castro would die in 2016. Manuel Noriega is mentioned but not seen, and is the last one known to be alive.
Peter's grandfather suggested that Bugs Bunny's name should be Ephraim the Retarded Rabbit.
A diplomat at the United Nations tells Peter, “I used to be a laughing stock around here until my country invaded Kuwait.” The diplomat is likely Tariq Aziz from Iraq and is referencing events of the 1991 Gulf War.
Actress Susan Sarandon appears to do an ad campaign seeking donations to feed the children of Petoria, i.e, Stewie. She says, “Many of you know me as Tim Robbins’ mother but I’m actually his girlfriend,” a nod to jokes about their 12 year age difference.
At one point while singing, Peter lauds his worldly experience, saying he's been from "Hartford to Back Bay", a neighborhood in Boston. Despite Peter's belief that that makes him worldly, those two areas are only approximately four hours apart.
In actuality, diplomatic immunity is not absolute, and there are differing degrees of immunity of heads of states. Diplomats who engage in a gross violation of American law, such as espionage, can have their diplomatic immunity revoked in agreement with the sponsoring nation, or can be banished from the U.S. persona non grata. In cases of war, diplomatic immunity is automatically revoked, so Peter being liable for trespassing on Joe's property was accurate.
During the scene at the UN, Peter demands a seat in the front row. Later on it is implied that the better your seat is depends on the importance of the country. In the real UN, all countries sit in alphabetical order, moving up one seat every year until the rotation goes around again.
A flashback shows Peter’s ancestor “Ulysses S. Griffin,” based on Union General Ulysses S. Grant, winning the American Civil War in a drinking contest against Confederate general Robert E. Lee. In reality, Lee was a teetotaler who claimed to have never drank.
Peter asks Horace, “Do you think Gordon Liddy paid for his drinks when he was strangling people with piano wire for the good of our nation?” Liddy was one of President Richard Nixon’s chief operatives in the Watergate scandal. Although he admittedly participated in several criminal acts and served jail time, he has never been charged with strangling a person with piano wire.
