Three North Koreans walk into a bar. They order a Ponghak, a Taedonggang, and a Rakwon. The bartender apologizes: they’ve only got a new beer, Ryongsong, on hand.

“No problem, we’ll have three of those!” says the Rakwon-drinker and goes to the toilet. The bartender brings three Ryongsongs.

The Ponghak-drinker takes a sip and grimaces in disgust: “That’s terrible.” The Taedonggang-drinker takes a sip and is sick into the glass: “This is disgusting.”

They storm out, leaving the glass of regurgitated beer. The Rakwon-drinker, back from the toilet, grabs the glass and, before the speechless bartender can interject, downs it.
