If you're Jeff Dawson, jumping out of a plane isn't enough. He'd rather do it naked. And he's done so 814 times. (And counting.) Believe it or not, it's harder to do a naked jump than a clothed one. And, the Guinness people don't keep records, so it's up to Jeff and his friends at SANS (The Society for the Advancement of Naked Skydiving) to keep the records.
