Ringling Bros. and Barnum & Bailey Circus was founded in 1919 with the merging of the Circuses owned by P. T. Barnum, James Anthony Bailey, and the Ringling Brothers. It is often touted as "The Greatest Show on Earth", and still tours (with two individual troops) today.
The Muppets have featured the circus on several occassions.
- In the Fall 1983 issue of Muppet Magazine, Kermit, Robin, Miss Piggy, Fozzie, Gonzo and Animal visit the Ringling Bros. and Barnum & Bailey Circus.
- In a Sesame Street video segment, David Larible, a clown from Ringling Bros. & Barnum Bailey Circus appears with his daughter.
- Dr. Bunsen Honeydew and Beaker appear at the famed circus in the Great Muppets in American History coloring book.
