The American comedian George Carlin in 1972 listed in his monologue "Seven Words You Can Never Say on Television". These are seven English-language words that are considered seven dirty words. In any civilized society, the words were then and now considered highly inappropriate and unsuitable for broadcast on large and small public airwaves.

In 1972, George Carlin released an album of stand-up comedy. The title of the album was "Class Clown". One track on the album was "Seven Words You Can Never Say on Television". In an oration, Carlin identified seven bad (dirty) words, expressing amazement that these particular words could not be used on TV, regardless of context.

Later Carlin truly hit a public nerve with his routine. He was arrested for disturbing the peace when he performed the seven dirty words routine at a 1972 show at Summerfest, an annual music festival held at the 75-acre Henry Maier Festival Park along the popular lakefront in Milwaukee, WI. It was reported by global media that Carlin faced problems in Cork, Ireland. Local authorities didn't like it when he publicly performed his comedy routine about "dirty" words. He was once again charged with violating obscenity laws.
