Looking for a creative way to have some fun and scare the crap out of your friends or co-workers at the same time?

A British costume compnay called "Morphsuits" is staging "fright mobs" This is basically when a group of ghouls dressed like extras from "Thriller" or "The Walking Dead" sneak up on your chosen victim while they are on the treadmill at the gym, or dilligently working at their office desk.

Morphsuits says 250 people have asked to freak their friends out with a "fright mob" They expect to stay busy straight up to All Hallows Eve itself.
