* BrokenBase: "Above The Noise". One half of the fanbase love their new electro-pop sound, the other half [[TheyChangedItNowItSucks just wants them to return to their old guitar-pop music ASAP]].
* CoveredUp: Their cover of "Baby's Coming Back" by Jellyfish is more recognised in the UK than the original. In America, neither are that well-known.
* EarWorm: Pretty much everything they've ever recorded.
** "[[http://www.youtube.com/watch?v=h76uVRSJ5bc Doo doo doodoodooooo DOO!]]"
* HarsherInHindsight: The video for 'That's the Truth', showing Dougie behaving in a depressed manner following a breakup becomes a bit cringeworthy to watch following reports that Dougie has gone into rehab after struggling to cope with his rather public breakup with long-term girlfriend Frankie Sandford, of girlband The Saturdays.
* HilariousInHindsight: [[http://www.youtube.com/watch?v=7Oe-VXqkp8s This video (Probably NSFW)]] in which Danny, Dougie and Harry mime/sing badly to Il Divo's Opera version of 'Without You' becomes all the more hilarious knowing that Danny would eventually appear as a celebrity contestant on reality show ''Popstar to Operastar''. For those of you who haven't seen the show, [[ExactlyWhatItSaysOnTheTin Danny, among other pop musicians, is trained to be an opera singer]].
** In the video for [[http://www.youtube.com/watch?v=1mUFbdW0XwY All About You]], the security guard (Played by [[Series/HarryHillsTVBurp Harry Hill]]) wears a badge saying "I'm a {{Busted}} fan". (Coincidentally the video was filmed on the same day Busted announced their split.) This becomes ''hysterical'' in light of the two bands teaming up for a [[http://news.sky.com/story/1166959/mcbusted-boybands-merge-for-uk-tour tour.]]
* HollywoodPudgy: In the early years, Tom was often mocked for being fat. He may have been slightly bigger than the other members, but [[http://i23.photobucket.com/albums/b382/Victoria2345/mcfly/39.jpg certainly not a fatass]]. He's lost weight since then, but Tom openly refers to his early-[=McFly=] appearance as "Fat Tom".
* HoYay: Dougie and Harry are often quite physically affectionate with each other. They might play this up as Fanservice. Any conceivable pairing between the four of them has its moments, though, do to the HeterosexualLifePartners nature of their relationships.
* ItsPopularNowItSucks
* JustHereForGodzilla: Arguably the only reason 'Just My Luck' got any success in the UK was because the fangirls were flooding in to see [=McFly=].
* {{Narm}}: 'Nowhere Left To Run' (TheMovie) is said to be full of this.
** Of course, many fans find the band's poor acting to be [[SoBadItsGood both hilarious and adorable]].
* NightmareFuel: The video for [[http://www.youtube.com/watch?v=Xlecfxv17PA "The Ballad of Paul K".]] Even the band themselves have admitted to being scared by it.
* SignatureSong: '5 Colours in her Hair' and 'All About You'.
* TearJerker: * 'She Falls Asleep', 'The Last Song' and 'The Ballad Of Paul K'. 'She Falls Asleep' is about a girl who is DrivenToSuicide, 'The Last Song', wanting to [[DyingMomentOfAwesome live the final moments of your life to the fullest]] and 'The Ballad Of Paul K' about a man suffering a mid-life crisis. The latter can be especially heartbreaking to those who have ever witnessed their own fathers going through the same thing.
** 'Down Goes Another One' about a loved one dying young. 'POV', 'Too Close For Comfort' and 'Bubblewrap' makes this Troper cry too.
* TheWoobie: The protagonist of 'The Ballad Of Paul K'.
** Dougie, following reports that he went into rehab to get over his difficult break-up.
