I think if I ever had to get an X-ray on my leg or something, I'd hide a piece of metal under my clothes that looks like a ninja star. Then I'd casually say "Oh that's an old battle wound..."
A little word to my Facebook friends. Stop accepting requests from scantily clad ladies in short skirts taking pics of themselves in the mirror. These are not real friends and you will end up having your FB wall pimped selling shoes. HELLO!?
