Irish Catholic is a term used to describe people who are both Roman Catholic and Irish (or of Irish descent). The term is not used to describe a separate creed or sect in the sense that "Anglo-Catholic", "Old Catholic", "Eastern Orthodox Catholic" might be. Neither does the term mean that it is an Autonomous ("sui iuris") Particular Church/Rite, such as Greek Catholic or Chaldean Catholic.

Divisions between Irish Catholics and Irish Protestants (both those who would eventually be called the Protestant Ascendancy and those Protestants of more humble societal position) have played a major role in the history of Ireland from the 16th century (especially the Reformation in Ireland movement) to the 20th century (especially The Troubles movement). While religion broadly marks the delineation of these divisions, the contentions were primarily related to access to power. For example, while the majority of Irish Catholics saw themselves as having an identity independent of Britain, and were therefore excluded from power, many of the instigators in rebellions against British rule were in fact Protestant. During the Irish Rebellion of 1798, both Catholics and Protestants other than those of the established, or British state church, found common cause, as they both endured discrimination based on not being part of the established church.

George Denis Patrick Carlin (May 12, 1937 – June 22, 2008) was an American stand-up comedian, social critic, satirist, actor and writer/author, who won five Grammy Awards for his comedy albums.

Carlin was noted for his black humor as well as his thoughts on politics, the English language, psychology, religion, and various taboo subjects. Carlin and his "Seven Dirty Words" comedy routine were central to the 1978 U.S. Supreme Court case F.C.C. v. Pacifica Foundation, in which a narrow 5–4 decision by the justices affirmed the government's power to regulate indecent material on the public airwaves.

The first of his fourteen stand-up comedy specials for HBO was filmed in 1977. In 1988, the 1990s and 2000s, Carlin's routines focused on socio-cultural criticism of modern American society. He often commented on contemporary political issues in the United States and satirized the excesses of American culture. His final HBO special, It's Bad for Ya, was filmed less than four months before his death.
