Remarkably, the sound of a witch cackling was recently voted the scariest sound in the world.
For those without an imagination, here is the sound in the form of written words:
AK-Ak-HEEEEE-HEEEE-HEEEEE!!
In previous years, the scariest sound was the sound of an angry dog.
But now it is a witch cackling.
Frankly, I prefer the dog.
