Do guys with big feet also have large penises? According to a recent study, there's not really much of a correlation. This flies in the face of an earlier 1993 study that did show a connection, although it was a weak one.

Before you ask, yes, these are actual scientific studies on penis size, done by urologists. There was another one done in 2011 that found height, weight, and body mass index are all linked to penis size. A second study done the same year found the size of a man's index finger correlates to penis size, which does make it curious that some studies have found shoe size doesn't. (You'd think if the size of other parts of the body had a relationship to penis size, then shoe size would as well.)

Have you ever thought exactly how researchers measure these penises in their studies? 

Turns out scientists use flaccid penises for their tests. If you ever decide to sign up for one of these studies, be aware that a researcher is going to be stretching, yes stretching, your penis before it's measured.

Turns out there is more than one way to stretch a penis.

Depending on how sadistic your researcher is, your penis may be stretched just once, after you drop trou, before its size its affected by the ambient temperature. Or, you could end up with the guy who stretches your penis THREE times, "the way a clown repeatedly stretches a balloon before inflating it and twisting it into the shape of a dog".    

All of a sudden, you've lost interest in participating in a penis size study, haven't you?
