Ties are totally random. They make no sense but everyone wears them. I wonder how a noose became fashionable.
Diamonds are the worse random thing. Some guy decides that this rock is valuable, makes people pay a million dollars for one, and now everyone wants one. What?!
I guess the king and queen of some countries are kind of random too. They don't have any power or special duties. They are just born into it. Just like that - and your face is printed on one hundred dollar bills all over the country. I wonder what that would feel like.
