No, not the guy from Alias. The island. The one that's part of the Bailiwick of Guernsey. I am not making this up. I couldn't make this up.
Sark is a small island in the English channel that, until now, was rented from the English Crown by a "seigneur," who ruled the island as its feudal lord, dispensing rents to citizens, given permission to staff the island with a military force, and who was the only person on the island allowed to keep pigeons or an unspayed female dog.
I was going to post the article, but the Wikipedia entry about the whole island is amazing.
Apparently to make it in the EU, they had to give up being feudal, which is sort of disappointing.
