The wife and I just watched the MST3K riff on The Dead Talk Back, which would be funny enough on its own. A woman is pinned to a door jamb with a curtain rod fired from a crossbow, and a paranormal investigator is called in to crack the case. Lusty apartment dwellers, furious itinerant preachers, dull-witted flatfoots, and jazz musicians all make an appearance. The dead may sass, but the living get the sassiest comeback: "Shut up, you potentate of righteousness!"
Long before White Noise, The Dead Talk Back made EVP the radio wave of the future. One of the five worst films ever made. Highly recommended.
