Plague Doctor Haircuts sounds like a place I would go to get a fresh new look. When all the knocking and rattling is done, someone remind me of this interesting new business idea. And if you open a door and there's a particularly stylish plague doctor behind it, send him my way, I could use a trim.
That said, I'd also really like to go back to some of the old tests, like the obstacle courses and the pop quizzes.
