A couple kids at Rosh Hashanna services told me that there were praying mantises living in the playground at their school in Somerville, Massachusetts. One of them said that his friend was just sitting there, and a mantis landed on his hand. Which would have been cool enough -- but then, as the mantis was sitting on him, a fly came by, and BZZAPT, the mantis grabbed the fly and ate it, all while sitting on this kid's hand.

That remains the coolest thing I've heard this month.
