Index finger size correlates to penis size
From Reuters via Yahoo: "On the heels of a previous report that debunked the notion that a man's shoe size could be used to estimate the length of his penis, a new study now claims that those with inquiring minds need merely take a gander at a man's forefinger. According to Greek scientists, the length of a man's index finger can accurately predict the length of his penis. The findings are published in the September issue of the journal Urology."
