The second and most brutallic crab is Internet Explorer 6. A glorious hedgehog in its day, I'm sure, but now so long overshadowed by its nobly shining successors that it has twisted up into a dark creature of hate which now hangs out with Gollum just to feel better about itself. We didn't expect the depths of its depravity and it's taking longer than expected to beat it into submission.
But we're getting close and may pull it off by tomorrow, crabs willing!
