Jonathan Lee Riches is renowned for filing numerous lawsuits in U.S courts. Some of his targets are actual living people, like Martha Stewart, George W. Bush, and Steve Jobs. But he has also gone after defendants like Nostradamus, Che Guevara, the Eiffel Tower, the ex-planet Pluto, the Holy Grail, the Appalachian Trail, and the Garden of Eden. This would be a good time for you to draw inspiration from his example.
I don't mean that you should become a litigious fanatic, but rather that you should seek redress and vindication from those people, places, and things that have not had your highest interests in mind. This could take the form of a humorous message, a compassionate prank, or an odd gift. Remember, too, that old saying: Success is the best revenge.
