Don't know if it's an urban legend or not, but my favorite is the story of the guy who everyone hated that bought a lottery ticket every week and left it in his desk. One week on the morning after the drawing, one of his co-workers stopeed and bought a ticket with the previous nights winning numbers, then replaced the man's ticket from his desk with the new ticket.
Upon arriving at work and checking his ticket, he proceeded to celebrate hi winnings, including telling his boss to kiss his posterior.
Wasn't till later that he was informed of the drawing dates...
Ohh, that's evil. Bump for later.
