Trivia: Fall Out Boy

  • Ascended Meme: "Thanks Pete" became such a popular meme after its appearance at the APMAs that the band created a shirt for it and now sell it in their store.
  • Hey, It's That Guy!: The video for their cover of "Beat It" features Donald Faison (Turk from Scrubs), Hal Sparks (Queer as Folk, The Soup) and Tony Hale (Buster from Arrested Development), with John Mayer on guitar
    • Most of their music videos also include a host of friends from bands on Pete's record label Decaydance.
      • Seth Green and Michelle Trachtenberg (both from Buffy the Vampire Slayer) show up briefly at the funeral scene in "Arm's Race", and Katrina Bowden who plays Cerie on 30 Rock is the mean girl in "Dance, Dance"
      • Brendon Urie and Spencer from Panic! at the Disco make an appearance in the video for "What a Catch, Donnie".
      • The "A Little Less Sixteen Candles" video has William Beckett and Mike Carden from The Academy Is..., Travie McCoy from Gym Class Heroes, and Brendon Urie and Spencer Smith from Panic! at the Disco all as various vampires from different clans. Travie McCoy also shows up in the video for "Dance, Dance" and "Arm's Race". Brendon and Spencer both show up again in the video for "What a Catch, Donnie" and "Headfirst Slide into Cooperstown on a Bad Bet". Brendon shows up solo in the video for "Uma Thurman".
      • Another "Dance, Dance" example, Ben Jorgensen from Armor For Sleep shows up, introducing Travie into the dance-off. This lead to Romance on the Set between him and fellow "Dance, Dance" cameo maker Katrina Bowden, who later got married in 2013.
      • Fall Out Boy's long time manager, Bob McLynn makes cameos in "Dance, Dance" as the principal, "A Little Less Sixteen Candles" as the priest, and as himself in "Uma Thurman"
      • Cassadee Pope, then of Hey Monday and later on of The Voice, cameos in the "America's Suitehearts" video.
      • The music video for "My Songs Know What You Did In The Dark (Light Em Up) consists entirely of 2Chainz and two other women setting fire to Fall Out Boy's discography and memorabilia.
      • Big Sean shows up in the video for "Alone Together", as set up for his appearance in The Mighty Fall.
      • Tommy Lee is the Devil in the video for "Death Valley", along with SOFI (aka SomeOtherFemaleInterest, known for her collaborations with deadmau5 and needing a ladder), as a turncoat member of the organization hunting down the boys that's willing to help them out. While this is Tommy Lee's first time in a Fall Out Boy video, this isn't SOFI's. She appears alongside Butch Walker briefly in the video for "This Ain't A Scene, It's An Arms Race" And last but not least, Elton John AS God himself!
      • The video for "Centuries" features DCD2 labelmate Lolo...and Rick Ross!
      • The video from "Uma Thurman" means Big Sean is tied with Travie for "Most Appearances By A Rapper In A Fall Out Boy" video. Appearances are also made by DCD2 labelmate Max Schneider, Action Bronson, Alan Wilkis of Big Data, and Brian Logan Dales from The Summer Set.
  • Hey, It's That Voice!
    • William Beckett sings in "Sophomore Slump or Comeback of the Year".
    • The other screaming voice on "I Slept With Someone in Fall Out Boy and All I Got Was This Stupid Song Written About Me" is Chad Gilbert of New Found Glory.
    • In "7 Minutes in Heaven (Atavan Halen)" and "20 Dollar Nosebleed", Brendon Urie lends his vocals. However, it may be hard to pinpoint his parts as he and Patrick have similar voices and singing styles.
    • In "What a Catch, Donnie", a few guest stars lend their voices to sing a few of their greatest hits.
    • Lil Wayne sings the bridge on "Tiffany Blews"
    • You know the second singer in "Save Rock and Roll"'s title track? Its only Elton Fucking John!
    • Courtney Love is featured on "Rat a Tat", Big Sean on "The Mighty Fall", and Foxes on "Just One Yesterday".
    • A non-musical example: Tara Strong narrates the opening of the "Miss Missing You" video for The Youngblood Chronicles. Her opening spiel is actually reversed text on the back of the Save Rock and Roll album.
  • Magnum Opus Dissonance: Patrick had a lot of high hopes for Infinity on High, his role in the album was mainly a response to thinking that From Under The Cork Tree' wasn't entirely deserving of the Grammy nomination it got. He explains more about it in the liner notes for the Believers Never Die greatest hits compilation.
  • Old Shame: Evening Out With Your Girlfriend, mainly due to the recording circumstances and the intent for it not to be released. Whenever the band discusses their history, Evening Out almost never comes up. "Growing Up" was acknowledged on "What a Catch, Donnie" and it made an appearance on the greatest hits compilation released before their hiatus, mainly due to it being the band's first song.
  • One of Us: One of their first tours in support of From Under The Cork Tree was the Nintendo Fusion tour, they did two alternate reality games for Folie a Deux and their Greatest Hits album, did an entire photoshoot with lightsabers, and on one of their blink-182 reunion support dates, they did a set dedicated to Lost.
    Andy: Uh...I'll put it in Game of Thrones terms: Don't wake the dragon!
    Andy: Or how about in Joss Whedon terms: The hammer is my penis.
    Patrick: Thank you...
  • The Pete Best: Fall Out Boy used to have a lead singer named Kyle Martino. He got kicked out before the band released an album.
  • Promoted Fanboy: As Chicago natives, they are long time fans of the Chicago Bulls. So the team asked them to create a new version their theme song, which they happily did in collaboration with fellow Chicagoan Lupe Fiasco.
  • Writer Revolt: A minor example. Their record company once asked them for shorter song titles, to which they responded by simply removing all the vowels from one title, producing "Thnks fr th Mmrs".
