* Legendary comedy team [[BobAndRay Bob & Ray]] based their entire act around this trope, as applied originally to [[RadioDrama the medium they worked in]], and later expanded to take in every media trend and fad going. Given their influence on modern American comedy - including but not limited to Bob Newhart and George Carlin - it could be argued that they played a major role in popularising the concept.
-->'''Bob:''' ''(introducing a "human interest" segment)'' We've found that you listeners enjoy hearing these pathetic people tell their tragic stories.
* First Officer Douglas Richardson in ''CabinPressure''. It's one of the things he does best, and he's good at everything.
* Ed Reardon of ''Radio/EdReardonsWeek''.
* One might miss it between CaptainObvious moments, but Arthur Dent in ''Radio/TheHitchhikersGuideToTheGalaxy'' was not above indulging occasionally.
-->'''Ford''': How would you react if I said I'm not from Guilford after all, but from a small planet somewhere in the vicinity of Betelgeuse?\\
'''Arthur''': I don't know. Why, do you think it's the sort of think you're likely to say?
** More obviously, Zaphod snarks at Arthur, Ford snarks at Zaphod, Trillian snarks at both of them and Marvin just snarks.
* The late Humphrey Lyttleton on ''Radio/ImSorryIHaventAClue'', whose chairman persona believed the entire game was insane, and the teams were clearly idiots for doing these things. (Except Mornington Crescent. ''That'' was SeriousBusiness.)
** The current host, Jack Dee, has carried on the tradition, with a few subtle differences. Humph was more bored, Jack is more bitter.
* Creator/PaulDarrow (best known as Avon in ''Series/BlakesSeven'') portrays one of these on Jack FM. He supplies all the recorded between song/advert/news/weather etc voiceovers in this style. (Jack FM is a "jukebox" style station with no {{DJ}}s apart from a weekday breakfast show.)
-->"Plans for CSI:Basingstoke were dropped after it was discovered no-one has any dental records and they all share the same DNA"
* Robin Ince in ''MitchBennsCrimesAgainstMusic''. And in real life.
* The Devil in ''Radio/OldHarrysGame'' is very definitely one of these, though most of the other characters get their moments.
* ''OurMissBrooks'': Miss Brooks' character uses sarcasm with frequency (as does many of the characters she plays in other works).
* Everyone in ''ThePhilHarrisAliceFayeShow'' has their moments, but Julius the grocery boy takes the prize. This trope defines how he enters a room and greets Phil and Frankie.
* In Radio/RidersRadioTheater, a great many of Woody Paul's lines, despite an earnest delivery, seem to absolutely drip with irony.
* Spock in the ''Spock Versus Q'' audio plays ''Armageddon Tonight'' and ''Did I say that?''. Technically, ''Q'' is the DeadpanSnarker for most of the latter play, but only because he's Spock. ItMakesSenseInContext.
