Pastafarianism (a portmanteau of pasta and Rastafarianism) is a social movement that promotes a light-hearted view of religion and opposes the teaching of intelligent design and creationism in public schools.

best source for data on the Pastafarian Church (or the Church of the Flying Spaghetti Monster)
