Rat king in the year of the rat

I saw this on Boing Boing, and since it's the Year of the Rat, it's just so appropriate.

What you see here is known as a Rat King. According to Wikipedia, it's

said to arise when a number of rats become intertwined at their tails, which become stuck together with blood, dirt, and excrement. The animals consequently grow together while joined at the tails, which are often broken.

Gross to the extreme.
