From Odile, from Arlington, MA:
The bluffing round just included an incorrect “correct” definition—the card defined “midden” as “a pile of nuts collected by a squirrel.” A midden is indeed a pile of nut-related material that a squirrel is responsible for accumulating, but it is neither collected by the squirrel nor, if the squirrel knows its business, are there any nutmeats in a midden. A midden is the pile of nutshells and other debris dropped by a squirrel as it eats. (Squirrels tend to sit on the same tree branch to eat, and the debris accumulates below.) It’s basically the squirrel’s garbage pile, which is how it relates to the archeological definition—a human midden is a trash pile of broken pottery, bones.
