All you have to do is prove to Robert Sungenis that the earth revolves around the sun, and he'll give you $1000!

If that isn't enough content for you, check out FixedEarth.com. I personally enjoy the advertisement for The Earth is Not Moving, a book which boasts the feature: "Non Moving Earth Illustration"! I figure it's like a flip book, but all the pictures are of Earth in the same spot.
I can't believe those are for real... wow.
