Attack of the 40 Foot Colon
A 40 foot colon is part of the National Cancer Education Tour to help educate people about the dangers of colon cancer. People can crawl through the "Colossal Colon" to view various stages of the disease. I wonder how this would work for other forms of cancer. You could have the "Large Lung," the "Behemoth Breast," and the "Prodigious Prostate." I bet you'd get a big audience for those last two.
