context_page_description: The Youth International Party, whose members were commonly called Yippies, was an American youth-oriented radical and countercultural revolutionary offshoot of the free speech and anti-war movements of the late 1960s. It was founded on December 31, 1967. They employed theatrical gestures to mock the social status quo, such as advancing a pig as a candidate for president of the United States in 1968. They have been described as a highly theatrical, anti-authoritarian and anarchist youth movement of "symbolic politics".
  Since they were well known for street theater and politically themed pranks, they were either ignored or denounced by many of the "old school" political left. According to ABC News, "The group was known for street theater pranks and was once referred to as the 'Groucho Marxists'."
context_section_description: Yippies organized marijuana "smoke-ins" across North America through the 1970s and into the 1980s. The first YIP smoke-in was attended by 25,000 in Washington, D.C. on July 4, 1970. There was a culture clash when many of the hippie protesters strolled en masse into the nearby "Honor America Day" festivities with Billy Graham and Bob Hope.
  On August 7, 1971, a Yippie smoke-in in Vancouver was attacked by police, resulting in the Gastown Riot, one of the most famous protests in Canadian history.
  The annual July 4 Yippie smoke-in in Washington, D.C., became a counterculture tradition.
