CHRISTOPHER: You know I don’t deserve that, I’m as mature as you.
LORELAI: What? The Offspring is your favorite band.
CHRISTOPHER: So? You’re into Metallica.
LORELAI: Well, Metallica is way more substantial than The Offspring.
CHRISTOPHER: Here we go, it’s the same Black Sabbath riff all over again.
LORELAI: Oh! The Offspring have like one chord progression. They use it over and over. They just popped on new words and called it a single, and I don’t want to talk about this anymore!
The Offspring is an American rock band formed in 1984 by Bryan “Dexter” Holland and Greg Kriesel. Their self-titled debut album was released in 1989, and they gained mainstream success in 1994 with their biggest-selling album, Smash. In 2001, their most recent album was Conspiracy of One, which came out the previous year. They were one of the most popular punk bands of the 1990s, and their biggest hits of this era include Come Out to Play (1994) and Pretty Fly (For a White Guy) (1998).
Metallica is an American heavy metal band formed in 1981 by Lars Ulrich and James Hetfield, and one of the founding bands of thrash metal. Metallica attracted a fan base in the underground music community while also gaining critical acclaim. Their 1986 album Master of Puppets was highly influential in thrash metal, while their self-titled 1991 album brought them wider mainstream success and is their biggest-selling album. In 2001 their most recent album was Reload (1997). One of the most commercially successful bands of all time, Metallica have won nine Grammy Awards, and were inducted into the Rock and Roll Hall of Fame in 2009. By these standards, Metallica would be judged as “more substantial” than The Offspring.
Black Sabbath, earlier mentioned, were an English rock band formed in 1968 by Tommy Iommi, Geezer Butler, Ozzy Osbourne, and Bill Ward. Often seen as pioneers in heavy metal music for their occult themes and image, their 1970 self-titled debut album was poorly reviewed, but a commercial success. By their 1973 album Sabbath Bloody Sabbath, they had begun to win the critics over while still remaining popular. The band broke up in 2017, and are often regarded as the greatest metal band of all time. Black Sabbath have won two Grammy Awards and were inducted into the Rock and Roll Hall of Fame in 2006.
A riff is a short repeated musical phrase, generally used as the opening or refrain of a song. Both being heavy metal bands, it isn’t surprising that Metallica sometimes have similar riffs to Black Sabbath – Black Sabbath were pioneers in the genre, so their riffs tended to set the standard for defining what heavy metal sounds like. A particularly noticeable example is the opening riff to Metallica’s 1984 track For Whom the Bell Tolls, and its similarity to the final riff in Black Sabbath’s 1970 track Fairies Wear Boots.
A chord progression is a series of musical chords played in a sequence. Certain chord progressions become very popular in certain genres, so it wouldn’t be surprising for The Offspring, like many other bands, to rely heavily on a certain chord progression. The Offspring often uses the I-V-vi-IV progression very popular in punk music, but so ubiquitous that it can also be found in songs by Bruce Springsteen, Coldplay, Celine Dion, Green Day, Madonna, Red Hot Chili Peppers, John Denver, and many others – it’s also the chord progression in Auld Lang Syne.
Christopher later says that he and Lorelai are arguing just like an old married couple, which he sees as a good sign for their relationship. Instead, you can see that they are arguing like a couple of teenagers, and that neither of them is mature enough for marriage.
