Have you ever been told something fantastical that turned out to be just an urban legend? This website can help you find out and keep you amused for hours.

Now, a website can help you out. Snopes.com contains the truth behind almost every urban legend that's out there, from the very old (no one will ever steal your kidney while you're on holiday) to the fairly recent (Harry Potter never really sparked a Satanic cult following).

So, if you've ever wondered at the truth of something you've been told, log on and prepare to tell the know it all that announced such a blatant lie as fact how full of it they are.

But Snopes isn't all about rumour busting. It also highlights which bits of trivia are actually true, which can be handy if, like me, you have a parent who panics over every bank fraud scam and computer virus scare that comes along.

It helps you know what to really watch out for, and will stop you from worrying about unreal threats, like kidney thieves! And, it's not just serious stuff on the site, but topics such as popular culture as well.

So now, you have no more reason to be sucked into believing that gullible is not in the dictionary.
