Bert Claster Productions was the company behind Romper Room, the American children's television franchise that began in Baltimore in the early 1950s and later spread through local and syndicated versions. Its closing logo became familiar to generations of viewers who grew up with the show. The sting uses Pop Goes the Weasel, a traditional folk and nursery tune dating to the 19th century, linking the company name to a tune children already knew. Today logo collectors, nostalgia channels and meme editors keep the clip circulating as a shorthand for vintage kids TV.
