Opening to "Cave Demon Roommate" (1984)

An upbeat, jazzy intro to the show's theme song begins. Edison explains the premise over the music; clips from the pilot episode tell the story.

"Rent was too high in the city, so I found a nice cave to move into. Well, 'nice' might be pushing it - it was okay. My first night in the cave was lonely, but I didn't know that Miles, a demon, was watching over me. We didn't exactly get along at first, but now we're the best of friends."

The saxophone solo from the intro ends and the theme song proper, "The Best of Each Other" (sung by Bobby Caldwell), begins playing over a montage of the following basic scenarios: Edison and Miles hanging out at a pet store (Miles eats a tarantula), going to the library (Edison wants to talk to a pretty girl, but can't), and eating ice cream cones on a park bench (Miles gets brain freeze). Back in the cave, they place a "Home, Sweet Home" sign crookedly over a pile of human bones.

Finally, the duo are shown on a mountain peak surrounded by swirling dark clouds. Edison clumsily hands Miles a sacrificial dagger, apparently meant for a goat that looks on nervously from the background. Instead of that gruesome act, Miles uses the dagger to divide a sandwich into three parts, one for Edison, one for himself, and one for their dark master, Forneus (played by reoccurring guest star William Hickey), who takes the biggest sandwich piece and open-mouth smiles to the camera.

The song ends on a freeze frame of Edison and Miles shaking hands while wearing cheerleader uniforms (also from the pilot episode). Over this still, the executive producer credits appear for Carla Reed, the Church of Putrid Decay, and Jerry Hewitt.

Each week's episode usually opens with an exterior shot of the cave.
