As with most televised "scientific" reports, this one is pretty worthless. Doesn't help that the first short guy has a receding hairline.
Yes, we are visual creatures. Men and women respond favourably to what is esthetically pleasing. But it's not the be all end all. Sort, fat, or ugly men have landed some seriously gorgeous girls by just having good game. I've seen some rather homely or bigger girls land some pretty good looking men the same way. Personality, body language, are a huge factor in attraction.
