* EarWorm: The theme song to ''When The Whistle Blows.''
** Not to mention "See his pug-nosed face! ''(Pug, pug! Pug, pug!)'' Little fat man with the pug-nosed face!"
* HarsherInHindsight: Creator/OrlandoBloom's insecurity about Creator/JohnnyDepp, considering his film career was practically dormant in between ''Franchise/PiratesOfTheCaribbean'' and ''Film/TheHobbit'' trilogies, while Johnny Depp had several leading roles in that time.
* HilariousInHindsight:
** Creator/KateWinslet cameoed as herself in an episode, where she announced her intention to star in a Holocaust film purely because such films [[OscarBait always win Oscars]]. A few years later, she finally won an Oscar for ''Literature/TheReader'', which is, you guessed it, a Holocaust film.
** The best part is that Ricky was a presenter at the Golden Globes that year - after she won he got up on stage and {{lampshaded}} the episode: "What did I tell you, Kate? A Holocaust film!"
** One of the ''Celebrity Series/BigBrother'' housemates in the Christmas Special is Lionel Blair, AdamWesting it up with the best of them. In 2014 he appeared on the show for real. ''Radio/TheNowShow'''s Sara Pascoe pointed out that while the parody episode only had him tapdancing around the house and complaining about being old, [[FreakierThanFiction the real thing had him pole-dancing dressed in latex.]]
** The Creator/SamuelLJackson episode features him getting confused with Creator/LaurenceFishburne. Funnily enough in 2014, a local news reporter interviewed Jackson and confused him with Fishburne in a very similar manner. Do note that this has happened to them enough that they'll tell stories about it.
* HollywoodHomely: {{Played with}}. Maggie often gets a number of disparaging comments about her appearance (especially by Creator/CliveOwen), even though Ashley Jenson is quite attractive. Of course, this trope is more {{Justified|Trope}} than usual considering she (by dint of her career in the film/television industry) ''is'' surrounded by extremely attractive women.
* HoYay: Darren and Barry.
* MemeticMutation: "Are you having a laugh? Is (s)he having a laugh?!"
* MisaimedFandom: Creator/RickyGervais was less than thrilled when "Are you having a laugh" ended up joining the ranks of the catchphrases that he considers to embody everything wrong with British comedy, and to this day he doesn't hesitate to tell that to anyone who quotes it in his vicinity.
* MoralEventHorizon: Andy finally crosses this line when he has an extra ''fired'' for coming up to him and asking him for the chance to try out a few lines, citing that he was in the same position himself; Andy shows no remorse about this, and promptly tells Maggie that ''she'' can't talk to him on set anymore.
* SeasonalRot: Though still considered pretty good overall, many felt that the second series suffered from becoming something of an AuthorTract about how all sitcoms that don't follow the single-camera ''Series/TheOffice'' / ''Extras'' style are low-brow garbage. Note that the vast majority of critics agreed 100% with this and complimented Gervais on helping point out the flaws in other comedy shows; their main complaint was that it overtook the humour on this show.
