World's creepiest death rituals

Tibetan sky burial:

A corpse is sliced up, usually atop a mountain, and left for the birds. Tibetans call the practice jhator, which means giving alms to the birds. And also legs, torsos and heads as well.
The bodies, wrapped in white cloth, are bought to the burial site, where the monks have enticed vultures and other airborne scavengers. Monks unwrap the bodies, a process that probably isn't all that pleasant considering they've been left alone for three days (per Tibetan custom).
