This 'guide to ambiguous grammar' is unexpectedly disturbing

Grammar: It's boring to talk about, unless you're that type of person. Which personally I am, though I recognize that the eyes of most normal humans glaze over like donuts at the very first mention of "tenses." Yet I implore you to push through that resistance and read this "interactive guide to ambiguous grammar" by Vijith Assar anyway. It goes somewhere genuinely important, so stick with it.
