Hold a summit of world leaders.
Get them all together in a room. Put (n - 1) chairs in a circle; these chairs have random code numbers assigned to them.
Music is played; when the music stops, every leader has to sit down on their nearest chair.
They then each open a sealed envelope corresponding to the code on the chair to discover which nation they're now in charge of.
The one left out gets to be U.N. Secretary General.
The nation "missing" a leader can either proceed on the basis that their current leader has died in office and choose a new one, or have the current U.N. Secretary General take charge.
What could possibly go wrong ?-- 8th of 7, Jan 19 2021 [-] not really much of an idea.-- Voice, Jan 19 2021 Still more of an idea than the actual leaders have, though.-- 8th of 7, Jan 19 2021 Well, no, we were hoping to trigger a number of small-scale military conflicts, then make money from selling weaponry to both sides and from the TV rights ...
It's not like we were looking for any positive outcomes (for humans, that is).-- 8th of 7, Jan 19 2021 yes, i too say, why not. there seems to be no rhyme or reason to what anyone is doing these days. +
I would insist that some would have to polka, Mexican Hat Dance, the twist. etc to along with the music.-- xandram, Jan 19 2021 Not sure about that ... you ain't seen ugly 'till you've seen politicians try to dance ...-- 8th of 7, Jan 19 2021 random, halfbakery
