The infamous leftist television-producer who only hires people whose appearance gives him a reaction "down there".

A railroad enthusiast that stands on bridges and films/takes pictures of modern everyday trains. Their obsession includes thousands of hours of footage of trains that no one knows what they use it for. If trains were people, rail-boners would be classified as stalkers.
