I recently read a lovely bit of satire by C.S. Lewis published in his book God in the Dock: Essays on Theology and Ethics and titled Xmas and Christmas: A Lost Chapter from Herodotus. It is about the holiday traditions of the people on the island of Niatirb (Britain spelled backwards).
I also found posted online here. (I'm unfamiliar with the linked to blog and so can't endorse what is said there and I'm pretty sure they violated the copyrights by posting it there, but at least now you can read it too :)
