The online fact checking and rumor busting site called Snopes has a real-time (as in updated daily) list of the latest Urban Legends.
Snopes is one of those sites on the internet that can become a real time suck if you’re not careful. I use it as a reference when someone forwards me an email about some odd warning/hoax, etc. You can usually get the truth about it and I’ve been known to reply with a link to the site (in the hopes they might do some research before blindly passing on bogus info).
