Night of the Living Dead

In this nearly wordless horror-movie spoof, a man in a suit and his frightened companion flee through the woods while two undead pursuers, a zombie cook and a zombie crossing guard, lurch after them moaning. The chase moves at a crawl: the woman keeps stopping to take off her shoes, the zombies pop up again behind a cornfield the couple thought had saved them, and the pair finally barricades themselves inside an abandoned shack. Chairs, a table and a lamp barely slow the monsters down, until the couple discovers the decisive weapon is a well-thrown shoe, leaving the man to wonder aloud how long their safety will last.
