Nick Horne appeared on the 47th David Letterman show. He is a comedian and expert physicist. Mr Horne is currently involved in "Smarty-Pants," a think tank which has solved many of the worlds pressing issues in addition to small ones (such as redesigning the zipper into the modern version seen today with locking capabilities - hence the name of his company)
Mr Horne plans on being one of the first men in space on a homemade craft. For 32 years he and his team have scoured junkyards for jet thrusters and other necessary parts. They expect their project to be completed in time for exodus by the 2012 Apocalypse (of which Mr Horne is a great believer).
