Why? Because it's just too symbolic and seen everywhere.
Wedding rings,
Sonic the Hedgehog,
toilet pee stains,
engagement rings from ex-lovers that you didn't care for but felt obligated to say yes to save yourself from embarrassment in front of the other people at the restaurant,
three ring circus,
He got it from Jared,
jaundice,
yellow ring of death on PS3,
class rings,
Beyonce "Halo",
light bulbs,
gas stoves,
smiley faces that have faded into oblivion,
80s christmas tree toppers,
that damn candle ring stain on your bedside table from when you kept it there for when you got into that melted wax fetish and forgot to put a candle plate,
crayon suns made by 2 year olds,
and gold medals that have been ironically bitten into during AP press photographs.
1) You're not even attached to anything but the yellow ring. If you were so important, you wouldn't be on the end would you? You think your friends will stand up for you? Just wait until the yellow ring disowns you and then where will you be? Yeah, think about that.
2) Prior to 1951 the rings were supposed to represent different continents. Black for Africa, Red for the Americas, Yellow for Asia, Green for Oceania and Blue for Europe. So basically in other words, Blue ring is the one given to the only non racist connotation. Good on you Olympics handbook writers. Seriously, and you had to put the blue one first. Because the Olympics are never racist.
3) It looks like a water ring stain. And if you live in my house, you use coasters. Condensation damage is not fun.
So this is why the Blue ring fell in fourth place.
