Keeping Up Appearances was given a viewer discretion warning after the classic BBC series landed on streaming service BritBox in 2021.
Created by Roy Clarke, the family sitcom featured Patricia Routledge as the unforgettable social climber Hyacinth Bucket and Clive Swift as her husband Richard.
The series, which first hit screens in 1990, chronicled Hyacinth's comedic endeavours to ascend the social ladder. Nearly three decades after the show concluded in 1995, all five seasons remain available for fans to enjoy on BritBox.
However, with the series featuring several jokes that have fallen foul of modern-day channel bosses, the streaming platform was forced to caution viewers with a content warning about the show.
BritBox alerted its audience that the much-loved '90s hit "contains language and attitudes of the era that may offend."

At the time, a spokesperson for BritBox said: "We review and refresh BritBox's programme catalogue on an ongoing basis," they remarked.
"Programming on the service that contains potentially sensitive language or attitudes of their era has carried appropriate warnings since our launch in November 2019, to ensure the right guidance is in place for viewers who are choosing to watch on demand."
In one episode of the show, Hyacinth and Richard retreat to her affluent sister and brother-in-law's house in the country.
During an encounter with a well-spoken man, Hyacinth informs Richard that the gentleman is "quent", meaning eloquent, and as "quent as a £4 note".
Another episode sees various characters ridiculing a Polish individual's surname and casting doubt on his entitlement to UK residency.

Plenty of British sitcoms have faced fresh cautionary notes in recent years, with classic 80s sitcom Terry and June becoming the latest TV show to be hit with a trigger warning for "discriminatory language".
The BBC show, originally broadcast from 1979 to 1987, starred Terry Scott and Dame June Whitfield as a middle-aged, middle-class couple, Terry and June Medford.
After dropping on ITVX in April, the broadcaster advised viewers on its streaming service that the iconic sitcom has "discriminatory language of the period".
ITV did not comment on the specific language used, however, a fan claimed on X: "There's an episode where Terry is at a work conference and puts June's perfume on by mistake.
"The entire episode is about how his boss hates gays, and how Terry is terrified about being thought of one. Cue every 70s homophobic comedy trope."
