I was working with this 1 guy at Canadian Tire, he was a big metal head, owned Dime Bag Darrel guitar, went to his house and he would just blast his amp in the garage, 100% black clothing, black hair etc. He told me about how he fled his old city in the east because his boss attempted to do some sort of insurance fraud and he involved him without asking and he told him that if he squealed he would be beat, so this guy was on edge, watching out for some thugs to come pulverize him.
The asshole would always sneak up behind me and attempt to scare me. Never worked. So I decided to try to start doing this to him. I got him pretty bad once or twice when I would sneak up behind him at work. He was eventually fired for getting into a fight with a co-worker who he made cry (she worked there longer and wasn't 100% death metal so she never got fired obviously). He ended up working right next door at the grocery store, doing the night shift.
So, I knew that he would take his lunch break around 2:00 am, and get back at 3:00 am. So what I did was I waited until he got back from lunch and I hid in the bushes across the parking lot and waited for him to start walking into the doors. I saw him walk back and I slowly tip toed behind him, slowly picking up my pace. Right when he was about to walk into the automatic doors, I SCREAMED really loudly and jumped on his back. HE JUMPED SO FUCKING HIGH. it was priceless.
I rarely get scared, but after watching the 4th harry potter movie at a harry potter marathon countdown to the 7th finale, I seen a big black dog take up my path ahead of me while I was walking down a dark and lonely sidewalk; this made me "irk" really badly because I knew that to be a bad omen via the movie. I brushed the dumb superstition off and began back on my way.
To be honest, I never get scared and that was one of the rare times that I have been. My gf has tried to scare me many many times and it never works, he never succeeded ONCE. The one time my gf did scare me was when I thought she was sleeping and she came up behind me at 3 am when I was coming out of the bathroom and I thought she was a fucking ghost because she was pale white.
Times when I have been REALLY scared... well... those are funny stories indeed that I won't share ;) wasn't so much of a spooked fear more like an awe fear... ???:P
