* AlternativeCharacterInterpretation: Is Jane really a desperate AttentionWhore, or is she more of a {{Troll}} that does what she does for [[ItAmusedMe the entertainment value]]? There are moments when she almost seems aware that what she is doing is ridiculous.
* EnsembleDarkhorse: Jeff. He's more or less the third main character, but far and away the most memorable.
* FridgeBrilliance: The first time we meet Oliver's ex-girlfriend Tamsin, he asks her if her breasts are bigger, and she tells him that no, they're just more inaccessible to him. But in later episodes, we learn that she is several months pregnant, meaning that yes, her breasts really were bigger, and Oliver is more perceptive than he at first appears.
* FridgeLogic: Which leads to a SugarWiki/{{Funny Moment|s}}.
** During the episode "Inferno," after Jane's very vague grasp of what vegetarianism is, we get this exchange between her and her therapist at dinner:
--->'''Jill:''' A vegetarian is someone who does not eat meat, you insane '''bitch.'''\\
'''Jane:''' I get enough of that language during our sessions.
** Realize that Jane is so screwed up, she has sent a licensed health professional so over the edge, she's insulted her repeatedly -- even calling her "insane," which is not a word psychiatrists are generally fond of. It was our first major glimpse into how messed up Jane really is.
--->'''Jill''': We agreed two months ago to end your therapy, it was going nowhere.
--->'''Jane''': I thought that was just an exercise to help me cope with rejection!
--->'''Jill''': No, that ''was'' rejection.
* FunnyAneurysmMoment: Jeff claiming his girlfriend Julia is dead is a lot less funny and way more depressing when her actress died of cancer two years after the show ended.
* HilariousInHindsight:
** During series 4, while Susan is coping with her pregnancy, the very vain Sally is very uncomfortable with the whole process. She mentioned in "Nightlines" how she doesn't really want a child, and mentioned how unsettling she finds it. In "Circus of the Epidurals," whenever Susan goes into detail about the actual birth, Sally ''faints'' and goes to her "safe place." When you learn that Kate Isitt (Sally) was actually pregnant during Series 4, it either becomes a hilarious in-joke from the people behind the scenes, or becomes unsettling to watch a pregnant woman face the gruesome truth about what's going to happen to her head-on.
** Steve including [[Series/DoctorWho Daleks]] among the things sofas are designed to protect from, given Creator/StevenMoffat's later career.
** In the episode "Bedtime" in series 4, Oliver wears a sweater that says "Bring Back ''Series/DoctorWho''". Considering [[Creator/StevenMoffat who writes the show]], and that a mere ten months after that episode aired, the 9th Doctor made his first appearance... even better, Jack Davenport's wife currently plays TheMaster.
* HoYay: Jeff imagining Steve nude.
* InformedAttribute: Jeff and Jane are the designated weirdos there, but the others are just as eccentric.
* OneSceneWonder: Jane's Aunt Muriel in "Sex Death and Nudity."
* ReplacementScrappy: Oliver for Jeff.
* RescuedFromTheScrappyHeap: Jane is a far more believable and likable character in season 4.
* SeasonalRot: Some believe the show went off the rails at the start of the fourth series, when Richard Coyle quit, Richard Mylan proved an inadequate replacement, and the Patrick-Sally relationship began to receive too much emphasis. Others believe the real rot began in the third series, where the laughs seemed more predictable and less spontaneous than before. Geoffrey Perkins leaving the BBC in 2001 (he was once described as an "enormous influence" by the ''Series/FatherTed'' writers) may have had something to do with this.
* TheWoobie: Jeff.
