My brother, 18 years older than I, and thus executed the following before I was born. A couple sisters of mine were having a get together with some friends in the upstairs portion of the house. My brother, had a friend over as well. Both were partial to army surplus equipment and therefore had gas masks, dark industrial clothes etc. When night fell, the set out to trip breakers, and cut power to the house. Occasionally turning the power off and back on, the stage of fear was set for the girls upstairs. With gas masks on, they cut all power and simultaneously made their way upstairs from the basement and the outside yelling, knocking on windows and scaring the he'll out of everyone.
