In all likelihood this is simply someone’s idea of a gag, but on the off chance that it’s not, we’re still going to pass on this public service announcement from the Vértes Volán regional bus services. As the sign states: “Dear Passengers, we ask you to please release your farts in the bus stop and not on the vehicle where it can disturb others.” Consider yourselves notified. [homar.blog.hu]
