When I was young, they used to sell x-ray glasses in ads in the back of comic books (young people, this is how we used to entertain ourselves back before the "internet"). These ads GUARANTEED you would be able to see chicks naked with them. IIRC, these cost $1,99, which is WAY less than a WBI machine, and every bit as effective at stopping terrorism. Wouldn't this be a much more sensible approach?
