Toads in Germany are mysteriously exploding, and scientists aren’t sure what’s causing it. I’ll bet it involves the introduction of nanomeds into their environment followed by large doses of gamma radiation.
(Yeah, yeah, I just rented Hulk. Not all that great; the movie was really trying for a “comic book” effect, and what it achieved instead was more annoying split-screens than 24.)
Update: The culprits might be hungry crows skilled at quickly pecking out toad livers. I guess that’s why we call a flock of crows a “murder.”
