Once upon a time, a group of diplomats from various European countries were flying over the Atlantic to a conference in New York.
They heard a loud "bang", followed by an announcement from the pilot. The plane was leaking fuel, and would not be able to reach land unless one of them jumped out to reduce weight.
The British diplomat stood up, shouted "God save the Queen!" and jumped out the hatch.
A bit later, the pilot reported that the fuel loss rate had increased, and another person would have to jump out.
The Soviet diplomat stood up, shouted, "Long live Comrade Brezhnev!" and jumped out the hatch.
A bit later, the pilot reported... well, you can guess.
The Dane, the Norwegian, the Icelander, and the Finn all stood up together, shouted in unison, "Long live Nordic cooperation!", picked up the Swede, and threw him out the hatch.
