Really Messy Divorce
In early Germany, the most popular way to resolve marital disputes was trial by combat. Typically, the couple would enter a ring and fight one another to the death. Well, sometimes they killed one another. Most of the time one of them would stop punching when the other person stopped moving.
Animal Trials
Back in the day, animals used to be subject to the same laws that human beings were. So, if an animal broke an arbitrary law, they would be arrested, held, tried, and either convicted or exonerated of their crimes in the same courts that people sat in. Sometimes the animals would literally be hanged in the same trials that people would get hanged in.
