I am astonished and disheartened that the legendary researchers at Cracked didn't include the Candiru

(Warning:  If you thought that the Cracked parasites were yucky and made your skin crawl, think twice before clicking this link or watching the videos.  Not suitable for work or family environments and truly the stuff of nightmares...because of the specific way that it interacts with humans.  You've been warned)

Stoat, I have to disagree. Cordyceps fungus is so nasty that it makes H. P. Lovecraft's works look like fluffy bunny stories.
