This one writes itself. CNN.com had a story about a special speed dating event in New York. The rules were not clearly specified on camera, but it appears that the women had to be young and beautiful, based on a judging panel's estimate of their photographs. The men had to have a net worth of a million dollars and (or?) income of at least $200,000 per year, with a higher minimum for older men.
Yes, it really was called Natural Selection Speed Dating. Paula Zahn's summary: "Deep cleavage meets deep pockets."
The organizer said they are planning a follow-up speed dating event, Sugar Mamas and Boy Toys.
