Jonah Falcon
Does he really have a 15" penis? Ron Jeremy said that while 13.5" was claimed about John Holmes, it was actually 12". Ron has said that Ron himself has 9.75", so to add over 2" on that would be crazy. From there, I can see why 13.5" was claimed - the figure also used for the Boogie Nights lead character, Dirk Diggler.
Jonah has some celebrity - I'm surprised that he would just be walking around in NYC like that. You would think he may be at risk of being raped. Perhaps he only walks in public places during the day. Still though.
