Spaghetti's Law 

A derivation of Godwin's Law, which states that as a Usenet discussion, primarily one religious in nature, the probability of an allusion involving The Flying Spaghetti Monster approaches 1.

Note: the Flying Spaghetti Monster is also interchangeable with gnomes, elves, unicorns, fairies, etc.

"Let's say I'm a devout follower of a god known as The Flying Spaghetti Monster. Now, let's say I support horrendously bigoted notions based purely on the word (Spaghetti's Law, or Biblesghetti) of this floating hunk of spaghetti. You don't feel that's a bit unfair?"

"If you want me to worship a flying spaghetti monster, or guilt me into believing that faith in the spaghetti monster is important, you must first prove that the flying spaghetti monster exists."
