* AccidentalInnuendo:
** The constantly-giggling "Uncle" Mike Stand was the undisputed master of these, which led to (deliberate by the writers) Unfortunate Implications, since he was a child show host. This was probably the in-universe reason why he was PutOnABus in later seasons.
** Certain names and titles had them; most notably the resident daredevil, "The oh-so-daring Mike Hunt" or debate programs with the title "Mass Debate." These were always pronounced ''very carefully.''
* SugarWiki/AwesomeMusic: Repeatedly. Every single episode of ''Radio Active,'' and quite a few episodes of ''KYTV,'' had at least one, often two, pre-recorded songs written by Phillip Pope and recorded by the cast, parodying various popular artists, genres or songs. One of them, ''Meaningless Songs In Very High Voices'' by "The Hee Bee Gee Bees" (parody of Music/TheBeeGees) even became a minor hit.
* TheCastShowoff: Creator/AngusDeayton studied German and it shows in his fluent delivery of German in episodes like ''Good Morning Calais''.
* EnsembleDarkhorse: Martin Brown. He doesn't show up until the fourth season of ''Radio Active'' and seems intended as a one-off character (as the episode ends with him being fired), but he returned after a couple of episodes and became the most popular of the recurring characters.
* GrowingTheBeard: ''Radio Active'' took until the second season to completely gel; the first season is amusing enough but suffers from a lot of EarlyInstallmentWeirdness (the presenters are largely interchangeable and personality-less, and the focus is less on their incompetence and more on parodies and eccentric guests) the writing is less sharp, containing a bit of repetitiveness and drawn-out jokes -- but by the second season the scriptwriters had found their groove and the show had found its form.
* RetroactiveRecognition:
** Debbie from "Challenge Anna" is played by Creator/SaraCrowe, who would later be best known for playing Fatima in ''Film/CarryOnColumbus''.
** Joan Patterson from "Get Away with You" is played by Creator/RosalindKnight, who would later be best known for playing Beryl Merit in ''Series/GimmeGimmeGimme'' and Horrible Grandma in ''Series/FridayNightDinner''.
* UnintentionalPeriodPiece: Mainly due to the adverts (a lot of which are parodies of then-current advertising campaigns) and the musical pastiches. Oddly enough, the rest of the show is much ''less'' dated than one would expect; in general, even if they're ostensibly mocking something specific, the parody still works in a more generic sense - for example, "Gigantaquiz" is a parody of a briefly-popular and now-forgotten game show called ''Ultra Quiz'', but it still works as a send-up of big set-piece game shows generally. The parody of ''Did You See?'' can be enjoyed as a send-up of arts discussion shows; "The Flu Special" which mocked the "AIDS: Don't Die of Ignorance" campaign, still works as a parody of public health campaigns, and so on.
* TheWoobie: Martin Brown, most definitely. Mike Channel too has moments of this, but is more of a JerkassWoobie.
