A friend's husband's blog pointed me to this, and I feel the need to propagate the meme since it made me laugh so hard. If you've eaten recently, wait a little before clicking on this link: Steve, Don't Eat It! Vol. 7: Cuitlacoche
Cuitlacoche is a black fungus that infects corn fields, making the kernels bulbous and swollen as they fill with spores. It also goes by the name Huitlacoche. If you're having trouble with the pronounciation, it's: Cuitlacoche (kweet-lah-KOH-chay) or Huitlacoche (dat-sfuckin-NAS-tee).
