Okay, this is just wacky:
Here’s what happened. A young man identifying himself as Caspian James Crichton-Stuart IV, 5th Duke of Cleveland, visited Stillwater Area High School in Minnesota three times trying to enroll as a transfer student. He had a “spot on” English accent and insisted on being called “your grace.” Students at the school had their doubts, so they began researching him on the Internet. They found Wikipedia citations regarding the Duke of Cleveland had been edited on several occasions by an anonymous Wikipedian - edits that were promptly corrected by other Wikipedians but still viewable in this Wikipedia edit history. They also found that someone named Joshua Gardner had created an entry for Caspian James Crichton-Stuart IV, the person who had visited the school. Subsequent student research exposed Gardner to be their so-called Duke of Cleveland; he also happened to be a 22-year-old registered sex offender.
