Five-Token Band: Sort of. Paul is the only one that's purely Scottish. Bob is English, Nick was raised in Germany, and Alex is half-Greek. Note that they don't really play this up, certain...ahem, fangirls do.
Name's the Same: the song "This Boy", which is not a cover of the Fab Four. The band is also named after a racing horse called The Archduke, which was named after the original Franz Ferdinand, as noted above.
Not Christian Rock: Nobody would ever accuse Franz Ferdinand of being a Christian band, but given "Auf Achse", "The Fallen", and a few other songs, it's pretty obvious that if nothing else, Alex's year of Theology at the University of Glasgow gave him a firm grip on Christian imagery (and a distinct vision of Christ, to boot).
Oop North: Other than Paul (who is Glasgow born and raised), the whole band originally hails from here. Alex spent his first eight years in Tyne and Wear,note Partially in the small city of Washington. As in George; it's where the first POTUS' ancestors came from. So Alex can claim to be "from Washington" and not be lying. Nick was born in Blackpool (and then grew up in Germany), and Bob is from West Yorkshire (Bradford to be precise).
Perspective Flip: at the end of "No You Girls", the lyrics are sung from a girl's point of view.
Recycled Lyrics: Taken to its logical extreme; "No You Girls" and "Katherine Kiss Me" are the same song, on the same album, with a different melody. In fact, the demo version of "No You Girls" is named "Catherine Kiss me", as seen in Alex's Soundcloud.
Retraux: The band loves all kinds of tasteful blast-from-the-past fashions, to say nothing of all the vintage equipment they use.
The Roaring Twenties: Their first album runneth over with the references to the '20s—especially in the videos, which are obviously influenced by Dada and Vkhutemas/Soviet Constructivism.
Self-Titled Album: their first one. Actually, originally every single album would be named just Franz Ferdinand, and the variation would be the cover, but the idea was dropped.
Sharp-Dressed Man: All four of them. Look at the page picture. Just look at it. Alternately, look at the video for "This Fire". It goes with everything they've done, too, from the Soviet Constructivist look of their first album to whatever you call they're doing now.
Shown Their Work: Sure, they may have been named for a horse rather than the assassinated archduke, but All For You Sophia shows they aren't ignorant of the latter.
Shout-Out: In the lyrics booklet, the line "come and dance with me" in "Michael" is preceded by a crossed-out "come all over me."
I'm on BBC Two now/Telling Terry Wogan how/I made it and/What I made is not clear now/But his laughter is and his deference is...
The deliberate use of collage techniques is reminiscent of Dada "art". Dada is a movement primarily associated with taking place during World War One, and the lyrics can be interpreted as being about the real Franz Ferdinand (although not as explicitly as "All For You, Sophia").
Unplugged Version: there is an acoustic version of "Take Me Out" on the "Lucid Dreams" single.
"The Fallen", "Twilight Omens", "Walk Away", "No You Girls", "Ulysses" and "The Dark of the Matinee" all have acoustic versions.
As does "Darts of Pleasure", under a different name.
Violent Glaswegian: Subverted by how the band started. Nick drunkenly stole Alex's bottle of vodka at a drunken party in (where else?) Glasgow. On the edge of a fight, Alex asks Nick : "Can you play the drums?" (as Paul was the one who originally played the guitar). It turned out he really couldn't, but they switched things around, and a band was born.
This fight may or may not have also ended with the two kissing.
