19. Hello Disney fans, And thank you for signing up for Bill Gates' Beta Email Tracking. My name is Walt Disney Jr. Here at Disney we are working with Microsoft which has just compiled an e-mail tracing program that tracks everyone to whom this message is forwarded to. It does this through an unique IP (Internet Protocol) address log book database. We are experimenting with this and need your help. Forward this to everyone you know and if it reaches 13,000 people, 1,300 of the people on the list will receive $5,000, and the rest will receive a free trip for two to Disney World for one week during the summer of 1999 at our expense. Enjoy. Note: Duplicate entries will not be counted. You will be notified by email with further instructions once this email has reached 13,000 people. Your friends, Walt Disney Jr., Disney, Bill Gates & The Microsoft Development Team. Example of a non-threatening Hoax Link to Other Hoaxes
