There Has To Be a Joke In Here Somewhere
But it's late in the blogging day, and we're too tired to come up with one -- so please make up your own punchline, and put it into the comments for this post. (Or send us a clever punchline by email, and we'll send you some comment invites in return.)
Update: As explained here , we are no longer accepting new "Jurassic beaver" punchlines. But we thank you for your interest.
