This is a “gag” clip about the heterosexual male preference for large breasted women.
See also this video (below), which is an excerpt from my 2010 presentation at the annual gathering of American Mensa. The last thing I say is: Every breast is large to an infant male.
If you wonder why homosexual males do not seem to focus any attention on the size of women’s breasts, see my published works on sex differences in behavior and the development of food preferences and sexual preferences. I first wrote about this in 1995 in “The Scent of Eros,” the book I co-authored with Robert Francoeur. Not only has the gag-video picked up on the connection from olfactory/pheromonal input to the heterosexual males preference for large breasts, Larry Young and Brian Alexander also borrowed our original representation for inclusion in their book “The Chemistry Between Us.”
See page 151:
“Male breast fascination begins there.
Later, in a recapitulation of those earliest days, we use breasts to help create and maintain the romantic bond. Breasts like penises have evolved into tools for stimulating oxytocin release via the mother-infant bonding neurocircuit.”
My comment: The mother-infant bonding “neurocircuit” is the clearest example of conserved molecular mechanisms that link the epigenetic ‘landscape’ to the physical landscape of DNA in the organized genomes of species from microbes to man. Attributing anything to a hormone such as oxytocin or any other hormone known to be involved in the neuronal feedback mechanisms that link the control of nutrient-dependent reproduction to pheromones, is a misattribution of biologically based cause and effect.
Obviously, Young and Alexander did not realize that the development of heterosexual male preferences for large breasts has more to do with the direct effects of pheromones on gonadotropin releasing hormone (GnRH). They attribute virtually everything to the hormone oxytocin. Thus, they also misrepresent the relative saliency of sensory stimuli throughout their book by linking everything to oxytocin via brain imagery. Clearly, however, the voles that Larry Young uses as his animal model are olfactory creatures, which links their monogamous or polygamous behavior to the sense of smell and GnRH, not touch and oxytocin.
It is the sense of smell that is most important to the chemistry between organisms like us (e.g., other mammals). See, for example, Olfaction spontaneously highlights visual saliency map. “…we reason it was spontaneous binding between congruent olfactory and visual information  that formed a multimodal saliency map where the visual object with added olfactory presence gained increased perceptual saliency.” What is currently known about hormone-organized and hormone-activated behavior puts GnRH first, and oxytocin much further away from any cause and effect relationship portrayed in “The Chemistry Between Us.“
