This reminds me of another story involving horses and, while not quite as formal as this, at least involved some creative (or humorous at least) argumentation.

This reminds me of another story involving horses and, while not quite as formal as this, at least involved some creative (or humorous at least) argumentation. A while back in Sweden some fella started a movement which argued that horses are in fact a fruit that does not exist. It became a quite popular meme and the founder was even interviewed on national television. (Yes, really.) When asked how a horse could possibly be a fruit that doesn't exist, he likened them to dragons. See, dragons are a kind of lizard, but they're also just a figment of our imagination and so therefore can not possibly exist. Horses are the same except they're a fruit, and they don't exist. He presented this argument with a straight face in the middle of a riding school with horses in the background, leaving the interviewer dumbfounded. It was a glorious and hilarious moment in Swedish television history.
