“A guy walks into a bar…” is a typical form of what has been called the “bar joke.” A political version is:
     
“A nihilist, a socialist, and a neo-marxist walk into a bar and order drinks. ‘We don’t sell alcohol to anyone under 18’, says the bartender.”
   
The joke is that nihilism, socialism and neo-marxism appeal to high school and college students, but not to people with real world experience. The political joke was posted on Reddit—Jokes on February 27, 2019.
