The episode: “The Slime People,” ep. 108
The riff: Spoken in a rather dopey-sounding voice by Crow as one of the “slime people” in the movie emerges from a sewer through the open manhole cover.
The explanation: This is an impression of the character Ed Norton from the sketches-turned 1950s CBS sitcom “The Honeymooners.” Norton, played by Art Carney, was the neighbor and sidekick of the show’s “main” character, Ralph Kramden, who was played by Jackie Gleason. Norton worked for the sewer company, and often called Ralph “Ralphie Boy,” thus the provenance of the riff. He was one of TV’s most enduring supporting characters, the Barney Rubble to Gleason’s Fred Flintstone.
Novelty factor: I definitely don’t know “The Honeymooners” well enough to pick up a reference like that. I know some of the basic tropes of the show (“to the moon” and all that), but the re-runs were already long past when I was a kid. It was actually a surprise for me to learn that there were only 39 episodes of the show’s original run. Given its place of prominence in pop culture, I always figured that it was a long-running series.
