One of Rob's and my favorite MST3K movies is "Boggy Creek 2: The Legend Continues." In it, a doofusy Arkansas college prof takes two students and a friend on a hunt for a Bigfoot-like monster who lives in the Arkansas swamps. A million poop jokes later, not much really happens.
But apparently the legend of the monster is real, even if the monster is not. Or, you know, vice-versa.
