If you can, go watch the movie, Wolf Creek, also known as Aussie Outback Roadtrip Goes Terribly Awry, also known as Never Trust Former Kangaroo Hunters In Hats. Did not pass out from sheer terror possibly because I was too busy shrieking and wolfing (hurhur) down peanut M&Ms.

Pretty gory too. Let's just say that the killer's trademark knife-and-spine trick called 'head-on-a-stick' is a figurative expression, not a literal one.
