I got a "Best Scare of the Night" trophy back when I worked at a haunted house. I was behind a wall with a drop panel and some guy left a huge grease smear from his hairdo across another wall.

Biggest scare i ever got was on a ghost train. Rounded the first corner, and tucked away behind the flappy door, only visible for about a second before a ghost on a stick popped out, was....

On the Ghoster-Coaster(suspended cage on rail), we were cracking jokes and giving s#!t to all the UV-light, rubber monster heads.
A staff member in a black suit and rubber-monster-gloves, that we couldn't see in the dark, reached through the bars of the cage and grabbed my friend and I.
Scared the piss out of us.

What scares me is dudes being paid minimum wage waving rusty things at me so obviously they're doing a bang up job
