 When Peter Sellers (qv) was chosen to guest star on an episode, he  requested that a skit known as "The Wall" not be done with him. In  this skit, Kermit interviews the guest for a short period just as  themselves, and Sellers stated that he couldnt be himself. "I can  be Queen Victoria, but I cannot be myself," he said. The writers  replaced "The Wall" with a skit where Sellers played Queen Victoria.
