* CoveredUp:
** Raise your hand if you thought "1985" was originally by them.
** "Stacy's Mom" managed to be a case of this ''before they covered it''. (As in, everyone thought they did it when it was really Fountains Of Wayne.)
* PeripheryDemographic: Despite many of their songs covering very adult content, they have a lot of teenaged fans, due to them having done a song for Film/SkyHigh, which many of those teenagers grew up with, and because they did the theme song for WesternAnimation/PhineasAndFerb, which has a PeripheryDemographic of its own. Lampshaded in "Friends Chicks Guitars."
-->''We've been in this band''
-->''longer than most of our fans have been...''
* SignatureSong: "1985" or "High School Never Ends". "Girl All The Bad Guys Want" is also one of their more popular songs, being their first song to really hit big.
** "Today is Gonna Be A Great Day" for their younger fans.
* TrueArtIsAngsty: Half the point of "I'm Gay" is to argue against this. (The other half is, well, [[HaveAGayOldTime you know]] . . .)
** By and large the band outright defies this as most of their songs are incredibly upbeat in nature, and even the angsty ones are noted to have a silver lining to them.
* {{Wangst}}: Mocked quite spectacularly in "Self-Centered".
-->''I'm gonna feel sorry for myself/I want to blame it on everyone else/I want to be self-centered/and make everybody feel sorry for me''
