1. POISONED CANDY
The most persistent Halloween urban legend of all is the idea that somewhere in your hometown lurks a sadist who’s poisoning the Halloween candy he’s giving out to random trick-or-treaters. In history, there’s only been one case of someone deliberately poisoning Halloween candy—but it wasn’t to random children.

This ancient urban legend isn’t entirely specific to Halloween, but many of its versions involve performing the incantation on Halloween night.

If you do this and see an angry woman staring back at you, it’s probably your mom, who’s just walked into your room and is wondering why you’re being so silly.
