When you're a member of the South Pacific Vanuatu, by the time you get to be eight-years-old or so it's high time to prove your masculinity. And what better way to prove you're ready to take on the challenges and responsibilities of adult life than stripping naked and bungee diving off a rickety 100-foot-tall platform?

Oh, and instead of stretchy bungee cables, they use vines. Those things that have been known to drop grapes and tomatoes every once in a while. They will show absolutely no give when you run out of slack and you're still hurtling toward the earth at hundreds of miles per hour. That will show no remorse when you plummet to your death. Vines.

The ritual is intended to impress both the gods and the ladies. Maybe you're thinking, "Hey, tourists do that sort of thing all the time! That's not so terrifying!" The Vanuatu people also realized that and decided that the gods would only be impressed if the boy's head touched the ground.
