A much-circulated online image purports to be a photograph of a sign from the "Airports Authority of India" advising travelers who are waiting in the terminal that "Shitting on Carpet Strictly Prohibited":
One clue that this image may not be on the level is that the Hindi writing visible on the sign conveys a very different message, namely that "(sitting and) eating on the carpet is prohibited."
Indeed, the above image is an altered version of the real sign, found at Chennai International Airport, which bears an admonishment in both in Hindi and English not to sit and eat on the carpet. However, even the appearance of the original sign was notoriously humorous, for a very different reason:
As UPI noted back in 2015, the Hindi text "Farsh par khaana sakht mana hai" should have been translated into English as "Sitting and eating on the carpet is prohibited" and not "eating carpet strictly prohibited."
