Bozo the Clown, a circus performer known for his distinctive red pointed hair, made his debut in a series of Capital Records children's albums/books (played by Pinto Colvig, the original voice of Goofy). He became Capital's mascot to the point where most of their children's records (with Bugs Bunny and others) were labeled as "Bozo Approved." Bozo achieved wider exposure in the fifties and sixties when Larry Harmon licensed and franchised the character as a children's show host in various cities, as well as producing an animated cartoon (with voices by Harmon and Paul Frees). Bozo went on to adorn punching bags, toys, comics, and other merchandise. The clown's name postdates the popular use of the slang phrase "bozo" to describe a fool or an idiot, although it since grew into wider usage as a synonym for clown.
- One episode, promoted as "Take a Vacation with Bozo Day", was taped at Walt Disney World, and included a portion of a performance of Muppets on Location: Days of Swine and Roses.
