How to scare kids sh*tless

I always try to scare the local kids on Halloween. In the past on a gig for John's school, we turned off all the lights then played the truly scary laugh from Frankie Goes To Hollywood's "Welcome to the pleasuredome." Puddles were left, and I'm sure a few squidgy cables were laid.
Another good way is to make a lantern with a scary face, so this year the boat is well and truly pushed out. So, the second post of the day is to show off my handiwork. Comments will be welcomed.
