9. Tying Intestines Around a TreeOkay, the technical term for this is disembowelment, which has been a pretty common practice throughout history. But there have been rare cases where the victims' intestines were pulled out, tied/nailed to a tree and then they were made to run around the tree which resulted in eventual death.
