Maybe you got a copy of this email? If not (and whether it is real or photoshopped, it is still scary) here it is.
Seems a sheep farmer was puzzled about the disappearance of some sheep on his farm. After a few weeks the farmer decided to put up an electric fence. About a week later, this is what he found! This is a Python & they're extremely aggressive & have a few teeth that they use to hold their prey while they wrap around them & then constrict. (Note: The wires are 10 inches apart.)
