Lookee here at what my wife found:
Mutter Museum, Philadelphia. Roadside America The Big Colon
One highlight is a giant colon that looks like a sand worm from Frank Herbert’s Dune � arranged with one end rearing up from the tastefully underlit display. Doctors were applauded for being able to correctly diagnose this whopper a gross enlargement of the colon and not as a tumor � without using X-rays. This digestive distension serves as an inspiration to new generations of doctors, and a warning to those of us who sometimes feel a little backed up.
