[Y]ou know what he wanted? Hot dogs! You know what they make those things out of, Chet? You know? Lips and a—holes!
—Dan Aykroyd, The Great Outdoors (1988)

There was a rumor going around my college that the beef served in the cafeteria arrived in boxes labeled “Grade E But Edible.” This was before the Internet was widely available, and Snopes did not yet exist. As it turned out, the rumor had been circulating throughout many college campuses. In reality, the meat wasn’t Grade E. Nor was it composed of, in the words of Dan Aykroyd’s character from The Great Outdoors, “lips and a—holes.” But it probably had its share of “pink slime.”
