A very good friend of mine once told me a story about how her brother's partner visited Paris, was drugged, and woke up in an alley feeling very unwell. He was taken to hospital, were it was found one of his kidneys had been expertly removed. I was dubious about it, but she told me she had seen the scar!

When I retold the story later, people laughed in my face. I guess I don't need to link to Snopes.

I'm just saying, one or two embellishments along the way can make all the difference in credibility...
