King Arthur and Merlin, I should be able to get something from that parade as well. :)

Ha, I didn't know that about Merlin! I do recall seeing his name written in Welsh as Myrddwn or somesuch.

HaShem? Not that I'm aware of. But there used to be quite a while back a few krewes with sufi and muslim themes. But as for "Big Kahuna," I suppose King of Carnival (Rex) might count...
