It appears that the writers of the Guardian need to have their mouths washed out with soap.
After receiving complaints from their readers about some of the more offensive words found in the pages of the paper, the editors discovered that they lead the world's newspapers in usage of a particular four-letter word referring to a woman's genitals (this is a term which is considered highly offensive, and I will not reprint, in order to foil search engine pervs). They also use the vulgar slang of "copulation" an average of twice per issue, and also have high counts of "crap" and "wanker". Their reaction to this can be found here.
