These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Anvilicious: Nearly averted, in a way. Despite being created with the purpose of dropping an anvil on the issue of female vicars, once the point had been made, the show moved on to more general insanity rather quickly.
Played straight with the Make Poverty History episodes, which were decidedly controversial due to making the last 8 minutes of one episode an advert for the campaign. The cast, and Dawn French in particular, have called Some Anvils Need to Be Dropped on this one.
Ear Worm: "Praise the Lord, he's coming down the biiiiiiirth canaaaaaaal!"
Fridge Brilliance: Alice believes that her pet budgie, Carrot, is the same budgie that she had as a child despite his repeated deaths and "resurrections" into bodies that look entirely different. Of course this would be plausible to a Cloudcuckoolander who is an avid fan of Doctor Who....
"Funny Aneurysm" Moment: Owen is made a godparent of Hugo and Alice's baby, whilst Frank and Jim are made "God-grandparents" because they "probably won't live much longer". Roger Lloyd-Pack (Owen) passed away in 2014, whereas Trevor Peacock (Jim) and John Bluthal (Frank) are both still alive.
Harsher in Hindsight: Casual namechecks of Rolf Harris and Jill Dando can be viewed this way, ever since Dando's murder in 1997 and Harris' conviction for paedophilia in 2014.
Hilarious in Hindsight: Not that it wasn't funny to begin with, but French and Saunders, the sketch show in which Dawn French (star of The Vicar of Dibley) and her comedy partner Jennifer Saunders first achieved real fame, had a sketch in which Dawn French dresses up in an over the top vicar's costume (complete with buckteeth and dandruff) and claims she has been cast as "TV's first female comedy vicar," not long before being cast as Geraldine, who may indeed be the first (or most famous) female comedy vicar.
Richard Armitage getting punched in the face during his wedding in Geraldine's Dream Sequence is funny enough, but somehow even funnier when you recall that the exact same thing happened to him in his aborted wedding to Marian on Robin Hood.
Hollywood Homely: Averted with Roger Lloyd Pack as Owen. Pack wasn't exactly an unattractive guy and Geraldine makes it clear that the reason she's not attracted to Owen is because of his disregard for personal hygiene.
One-Scene Wonder: Hugo and Alice's wedding is interrupted by a woman who storms in with a marriage certificate, insisting that the groom is already married to her. Hugo turns around in shock, at which point she says: "Oops, wrong church!" and slips away again.
Retroactive Recognition: With some of the smaller parts on the show, featuring actors who've made bigger names for themselves in the years since. For example, Skins fans will recognize Tristan, the hunky BBC cameraman, as Sid Jenkins's dad. The Thick of It fans may likewise recognise the same actor, Peter Capaldi, as Malcolm Tucker; others might recognise him as the 12th Doctor. Also, Miranda Hart of Miranda pops up as a dating agency official and Lord Grantham as the minister who officiates over Geraldine's wedding.
