In England when someone farts they might say "More tea vicar?"
When did this start, and how did it come about? It feels unusual enough to have a definite creation – some comedian perhaps? Web searches for ["more tea vicar" origin] or ["more tea vicar" etymology] do return results, but they're low quality and don't answer the question.
(I don't think it's in Brewer's Dictionary of Phrase and Fable either, although I could be wrong)

Nigel Rees actually published a book titled More Tea Vicar? An Embarrassment of Domestic Catchphrases (2009), but its entry for that phrase is disappointingly vague:
Rees (again) in A Word in Your Shell-like (2004) provides additional information on the phrase:
On the other hand, Julia Cresswell, The Cat's Pyjamas: The Penguin Book of Clichés (2000) indicates that "More tea, vicar?" was a catchphrase associated with sedate gentility before it got commandeered by jokesters:
In any case, a Google Books search doesn't turn up any matches at all for "more tea, vicar" before 1981, when the phrase appears in New Zealand Alpine Journal, volume 34, not in the context of farting or complacent gentility but of a surprisingly easy ascent:
Under the circumstances, I think that the circa 1985 date put forward by The Concise New Partridge Dictionary of Slang and Unconventional English (2015), noted in Josh61's answer, is far closer to the mark than Nigel Rees's "from the 1920s/30s?" as the starting point for saying "More tea, vicar?" after someone farts.
