Take on the weird plug thing

I have been on 4 continents, 40 countries and 16 time zones but I
still have no idea which place uses the plug which includes the thick
middle plastic one. Whether you go to China, Egypt, Belize or
Romania you get away with either the US connector or the European one
but when you get your hands on one of those universal one there are
two connectors which seem like they would be used by aliens. I
honestly have no idea who is using this thing but have to think it's
being uses only by places like New Guinea or Zimbabwe and honestly if
you want to attract ANY tourism the first thing you may want to think
about is getting a normal outlet.
