If you have wondered about the veracity of the tale of the woman who used a microwave to dry her poodle, or bought into the idea that Jamie Lee Curtis is a hermaphrodite, or that Stan Laurel was Clint Eastwood's dad, then Snopes should help you to separate fact from fiction.
Dedicated to testing the truth behind urban myths, Snopes is meticulously researched, always enlightening, occasionally alarming and sometimes very funny. For me, the most interesting part of this endlessly intriguing site is the one devoted to rumours currently being peddled by the net's conspiracy theorists, including the one that Mars will make a close orbit of the earth just three weeks from now.
Snopes is the perfect weapon for smartarses who want to show other smartarses why they are wrong.
