Who doesn't like a good fright every once in a while? A scare that let's us know we're alive, helps us laugh at ourselves, enjoy life... and even understand why life is worth living! In the spirit of Halloween, here are some of the scariest ads we've ever seen, whose marketing genius haunt our dreams and buying behaviors. Check out our top picks and tells us about some of your frightening favorites.

Dirt Devil

Great advertising puts a twist on our expectations, and Dirt Devil truly delivers a good one in this parody of the Exorcist.

Snickers

How far would you go to get your favorite Halloween candy?

Alcohol

For children, the worst monsters can be the very people who are supposed to protect them.

Nike Running

It never ceases to amaze us how the monster would always walk so slow in movies, but always catch up to the damsel in distress. I guess she wasn't wearing Nikes.

PlayStation 3

The folks at Sony deliver a truly spooky experience with this ad for the PlayStation 3.

Axe

Axe ads are usually pretty creepy without the theme of horror running through them. However, this one delivers an amusing twist to horror movie cliches.

Anorexia

Some of the scariest things in the world are what we do to ourselves. This PSA for Anorexia makes an intentionally disturbing case for helping people suffering from eating disorders.

Meth

Darren Aronofsky delivered a series of Meth ads that put us in right into the horrifying lives of addicts and their families.

Baby Laugh A Lot

Did they hire Alfred Hitchcock to direct an ad for a children's toy? I was in disbelief at the unintentional creepiness of this commercial. I still think I'm being punked, and just can't find the original ad.
