Ring around the rosey,
A pocketful of posies.
ashes, ashes.
We all fall down.

Such a creepy childrens song, gosh darnit. and even if it doesn´t mean anything, it´s still creepy, yo :/

Close your eyes and imagine that you are in the past, on the British soil during a nice massive plague and suddenly hou hear the faintest sound of creepy melody sung by children somewhere near the street but you can´t see because of the fog, smoke from the flames of you dont know what. The weather is far from perfect and for a springtime, it is too cold. Just walking towards the singing kids, you hear "ashes ashes we all fall down." Then a blow of wind and the air clears to the direction you were looking at and you see the poorly dressed and malnurished children in a circle, fallen down. A gang of rats is making their way to the children, laying on the ground. Rats just run over and by them, doing the children no harm. Yet, harm was done by the insects who carried out the plague even to the people who were not leaving the house.

as i read from wikipedia, ("In Louisiana and some parts of Southeast Texas, it is usually sung") dunno bout the reliability but if that is the case, the southerners were creepy in their own way,

In Louisiana and some parts of Southeast Texas, it is usually sung:
Ring around the rosey,
Pocket full of posies.
Upstairs, downstairs.
We all fall down.

and it came from a rather innocent, yet still unmistakably creepy set of lyrics like this when they didn´t fall to ashes but rather just sneezed. it goes:

Ring a-ring o' roses,
A pocketful of posies.
a-tishoo!, a-tishoo!.
We all fall down.

but the tune is oh so freaking creepy
