"And this shows that people want to be stupid and they do not want to know the truth. And it shows that something called Occam's razor is true. And Occam's razor is not a razor that men shave with but a Law, and it says: Entia non sunt multiplicanda praeter necessitatem. Which is Latin and it means: No more things should be presumed to exist than are absolutely necessary. Which means that a murder victim is usually killed by someone known to them and fairies are made out of paper and you can't talk to someone who is dead."
