It's time to clean out my email...
So for the next few days I'm going to be posting all kinds of stuff that I emailed to myself so I would remember to blog it...no matter how old it is!
First item, which you may have missed on August 9th of this year: CNN: Explorers find world's deepest hole.
Wouldn't you know it? It's got LEECHES at the bottom!
That's why people should never go outside. There are very deep holes. And leeches.
[Update, January 8th - the CNN link died, here's a pdf version.]

I should add that it's "one of the largest known colonies of subterranean leeches." Just for the sake of completeness.
Quote (approximately) Bill and Ted:
"Whoa, this is a totally deep hole!"
"Yeah!"
