Halloween is one of the few days Pastafarians can walk around in traditional dress (pirate regalia) free from judgement and persecution. People on this blessed day also seem generally open-minded / perhaps drunk, so may be more open to hearing about the virtues of the Flying Spaghetti Monster and our religion. All in all, it is a prime evangelism opportunity — I hope that everyone makes the best of it and enjoys the day.
Special thanks to all of the Pastafarian Missionaries spreading the Word.
