It’s Talk Like a Pirate Day, and here’s my annual plug to visit The Mudd’s witty homepage — more than a laugh a minute — and also to check out Peter Leeson’s excellent work s on piratical organization, The Invisible Hook.

If you don’t have time to read the whole book today, you can read one of the many favorable reviews instead.   For the more scholarly version, check out Leeson’s original Journal of Political Economy piece.
