I once got this email about a female entomologist who got infected with this burrowing worm type thing that hatched in one of her breasts. They had pics and everything.
I checked it out on Snopes and it transpired to be a fake, someone had photoshopped a lotus pod onto her breast and made a very good job of it.
That was over a year ago and I still feel queazy thinking about it now! The chap who sent me the mail said he affected him for a few weeks after as well, it was disgusting, the kind of thing you cant get out of your head for ages after.
