Cut his feet off, boil them, force feed them to his family infront of him and poo in his letterbox, then wipe the poo on his bleeding stumps, then boil the stumps and force feed them to himself infront of his family then and only then...
...move on with your life because it really is trivial.
(and boil his family)
