Murphy's Razor

the principle that the best method of surviving a horrific situation is to simply leave, posited by Eddie Murphy in his long-form standup comedy film Delirious; "it's very simple; if there's a ghost in the house, get the f**k out the house"

in Eden Lake, when faced with a bunch of abusive ASBO kids with a Rottweiler, Fassbender should simply have employed Murphy's Razor and gone to a Holiday inn instead of camping in the forest.
