In 1882 an internal dispute between the compositing (layout and typesetting) department and the editorial staff of The Times of London led to an incident that can best be described in modern terms as "Victorian Shitposting."
A speech by Home Secretary William Harcourt was selected by the editors to be reprinted in full due to an upcoming by-election. The conclusion of the Rt. Hon. Gentleman's speech was, in the edition that went to press and was distributed across England the next day, quoted as follows:
I saw in a Tory journal the other day a note of alarm, in which they said “Why, if a tenant-farmer is elected for the North Riding of Yorkshire the farmers will be a political power who will have to be reckoned with." The speaker then said he felt inclined for a bit of fucking.
The reader could be forgiven for wondering if Sir William had in fact said this, or had perhaps been misquoted.
Victorian Furor followed. The Times ran a mortified apology four days later and left no stone lie in its attempt to find the perpetrator. A few months later (presumably he) struck again. An advertisement for a book called Everyday Life in our Public Schools was altered to claim that the book was bolstered by "a glossary of some words used by Henry Irving in his disquisitions upon fucking."
Many employees of the compositing department were given the sack. It is unclear if the guilty person was among them, or merely was scared into ceasing his endeavors by the consequences handed down to his co-workers. In either case the incidents stopped and did not return.
Truly was this a great moment in the history of culture-jamming, pranking, civil disobedience, or whatever one chooses to call this kind of brilliance.
