Via Boing Boing: The Guinness Book of Records people have appointed a new winner for the title of the world's smallest horse. The unimaginatively named Thumbelina, owned by Goose Creek Farms in St. Louis, is a tiny tiny 17 inches tall and weighs only 60 pounds. She comes from a line of miniature horses to begin with, but she's about half the size she should be, which means she's a dwarf miniature horse. Seriously. And she's got her own website, of course, and since it's on the internet, it must be true.
