Walking into (or onto) a swamp.
Today 9 of us went swampwalking at a swamp at Greenwood Park in Northern Broome County NY. It was all ice. Try it in spring if you want to walk "into" the swamp.
Simple diarrhea, preferably brown in color. Should not be the consistency of water. More like the gravy served at Thanksgiving which consists of plenty of white flour.
After eating at KFC two days in a row the greasy chicken produced a light brown flow of sphincter gravy.
