Perhaps He would wear this spiffy Flying Spaghetti Monster Crocheted Hat. Self-referential, sure, but great for keeping the ol’ strands cosy and dry.

The Flying Spaghetti Monster Hat
The Pope has a special hat. Rabbis have special hats. Rastafarians have special hats. Why not Pastafarians?
This hat is crocheted (I assume you could knit something similar). Unfortunately, I don’t how to write patterns — my grandma taught me how to crochet in a rather freeform manner (she also made the best spaghetti and meatballs, EVER – coincidence?). So here’s a very rough guide…
Now put on your hat and waggle your noodly appendages in His name — you’re warm, blessed, and look like a complete dork. AMEN.
I’m sure she meant to say RAmen.
Meanwhile, I think we can see in this video an unheralded, early sighting of FSM Himself. His vengence is terrible: I miss the Swedish Chef so much…

First it was the church of scientology and then the pastafarians… What new and weird religion will spring up next I wonder? If you check out the article in Wikipedia to do with scientology, you notice that when it comes to creating a strange way for the touchy subject of human evolution to be re-written, these guys are number one :)
I’m too a-skeert to read about the Scientologists after what Fat Joe Thomas said about Dianetics.
