McShit
A friend of mine, on leaving McDonald's after years of underpaid, unappreciated work there, including long hours, and always working weekends, which included getting to see the sickening manner in which the 'food' there was stored and then processed into Chav-Meals, did the following:

Being one of the few people knowledgable about t'internet, it being the north, and about 1997, found a fetching website of a lady and a gentleman indulging in adult fun of a scatological nature, which culminated in said lady eating the gentleman's brown trout right out of his chocolate factory. His parting shot was to place said picture on every computer, as screensaver, wallpaper, and in various business files, in about 3 branches across Manchester, replete with the title 'Welcome to McDonald's'.
