Got an update on the exploding frog story:

Birds May Be Behind Exploding German Toads

BERLIN - Why are toads puffing up and spontaneously exploding in northern Europe? It began in a posh German neighborhood and has spread across the border into Denmark. It's left onlookers baffled, but one German scientist studying the splattered amphibian remains now has a theory: Hungry crows may be pecking out their livers.

Investing tip: this is going to cause frog liver futures to skyrocket.
