YOU ARE ALL FUCKING THIS PAGE UP. Because you want to make your own country looks better. Whoever removed the Aussie and NZ part is an idiot. Also the suggested theory of how the yard glass came to exist is incorrect. I have posted it before with proof amoungst other facts about this but some people seem to want to always delete things. I'm over it. 
 Wikipedia is too hard to work out how to edit everytime I have something to correct.
