The Colossal Colon is coming to a city near you: "As part of March's National Colorectal Cancer Awareness Month 2003, the Cancer Research Foundation of America will lead a nationwide, 20-city Colossal Colon Tour from March 2003 to October 2003... The Colossal Colon is a 40-foot long, four-foot high replica of a human colon. Visitors who crawl through the colon, or look through the viewing windows, will see healthy colon tissue, colon disease, polyps and various stages of colon cancer." (Via Metafilter.)
