The man with the worlds largest penis had it measured by Guinness world record books and verified as 12 point something inches (nearly 13 I rounded to closest inch)

If this is Jonah Falcon he's a fraud who Guinness has on several occasions had to publicly denounce because people keep running headlines saying he's in their book when in reality they've never even met with him because he refuses to. Another example of how people have a tendency to believe absurdly big lies because why would someone lie about something so easily verifiable. Jonah does have a very large penis but no, he's not 13 inches. The biggest penis ever measured in a study was just over 10 inches, but that was a BP measurement.

My penis was once in the Guinness Book of World Records.  Now I’m banned from the library.
