Happy Twilight Zone Thanksgiving!

Thing I like the best about Thanksgiving is The Twilight Zone marathon on one of the local channels.  I've already seen two episodes I've either long forgotten or never saw to begin with; one in which Roddy McDowell finds himself in a museum-like living room that displays humans in "their natural habitat" -- an idea that George Saunders later blew through the roof in the title story of his collection, Pastoralia; and a rare sentimental oddity in which an elderly couple have the opportunity to "trade in" their old bodies for younger models.
