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)
