A soap opera is an ongoing, serialized work of fiction, usually broadcast on television or radio. The term originated during the radio era in the 1930s, derived from the fact that soap manufacturer Procter & Gamble was the most prominent early sponsor of such programs. Trademarks from the early days of soaps include overwrought emotional outbursts, dramatic organ music, and a somber-voiced announcer posing questions about the storyline. The Muppets have spoofed this format many times.
- "Veterinarian's Hospital" is a regular spoof on The Muppet Show of medical soaps like General Hospital and The Doctors as well as Vaudeville comedy acts.
- Muppet Madness includes a parody called Our Turning World.
