The Muppet Halloween Show

The Muppet Halloween Show was a special proposed in the early 1970s, that ultimately served as the foundation for one of The Muppet Show pilots.

A script excerpt describes one of the special's characters:

Dr. Bredlow Freedly is the Muppet scientist who invented MEL (short for Malfunctioning Electronic Logician). Freedly attempts to demonstrate the newest use for this mechanical marvel -- first, the machine will inhale our polluted air. It will then condense the smog, fumes and filth into handy little cubes for shipment to the less industrialized countries of the world. (Zounds! We'll make a fortune!)
