I have seen one bigger than my own but it's not a pretty story. I visit a Urologist from time to time and some years back I had the need to see him somewhat regularly. On one occasion I needed to use the men's room just outside the office. There, in front of one of the two urinals, was a guy who's penis was about 18 inches long - it was also ribbon thin and reminded me of pictures of tapeworms you'd see biology text books. The guy was wrapping it up like a garden hose. I felt sorry for the guy; my problems seemed to pale next to his.
