Chubby Checker lawsuit: Does shoe size correlate with penis size?

Chubby Checker filed a lawsuit against computer giant Hewlett-Packard last week after the company released an app called “The Chubby Checker,” which purported to estimate a man’s penis length based on his shoe size. A 1993 study observed a relationship between shoe size and penis length, albeit a weak one. The same year that the English study claimed to bust the shoe-size myth, Greek urologists observed a relationship between penis length and the length of one’s index finger. If the size of other body parts correlates with penis length, it would be surprising if shoe size did not.
