You know what they say about big feet?

...It's only a nominal coefficient with penis length. 

Here is the abstract from the above interesting "research"....

Abstract  To determine whether "folk myths" regarding the relationships of penile size to body height and foot size have any basis in fact, 63 normally virilized men were studied. Height and stretched penile length were measured; shoe size was recorded and converted to foot length. Penile length was found to be statistically related to both body height and foot length, but with weak correlation coefficients. Height and foot size would not serve as practical estimators of penis length.

Thus "professionals" and "researchers" have "scientifically" determined precisely what every last non-virgin on the planet could tell you...You can't tell until the drawers drop and Mr. Snuggles is prepped for action.
