a crack in your ear through which sound surreptitiously slips, or an illicit substance which gives your ears immense pleasure while enslaving them to a crippling addiction
The Tonight Show would never ever feature something like this now, but in 1974 things were much different. That's when they featured Jim Henson performing this very surreal, adult, and un-Muppet puppet show. Raymond Scott composed the score (you can hear a few bars from "Soothing Sounds for Baby" in there).
The sound is a bit muffled on the high end, so you'll want to turn your speakers up a bit for this, or eq it if you can...
