Seven dirty words

“The seven dirty words are seven English-language curse words that American comedian George Carlin first listed in his 1972 ‘Seven Words You Can Never Say on Television’ monologue. … At the time, the words were considered highly inappropriate and unsuitable for broadcast on the public airwaves in the United States, whether radio or television. As such, they were avoided in scripted material and bleep censored in the rare cases in which they were used. Broadcast standards differ in different parts of the world, then and now, although most of the words on Carlin’s original list remain taboo on American broadcast television. The list was not an official enumeration of forbidden words, but rather were compiled by Carlin to flow better in a comedy routine. Nonetheless, a radio broadcast featuring these words led to a Supreme Court 5–4 decision in 1978 in FCC v. Pacifica Foundation that the FCC’s declaratory ruling did not violate either the First or Fifth Amendments, thus helping define the extent to which the federal government could regulate speech on broadcast television and radio in the United States. During a performance in 1966, comedian Lenny Bruce said he had been arrested for saying nine words. … In 1972, comedian George Carlin released his fourth stand-up album Class Clown. One track on the album, ‘Seven Words You Can Never Say on Television’, was a monologue in which he identified these words and expressed amazement that they could not be used regardless of context. … Carlin was arrested for disturbing the peace when he performed the routine at a show at Summerfest in Milwaukee in 1972. On his next album, 1973’s Occupation: Foole, he performed a similar routine titled ‘Filthy Words’, dealing with the same list and many of the same themes. Pacifica station WBAI broadcast this version of the routine uncensored on October 30 that year. …”
