Early in the ep, she declares herself to be Black Jackson, pirate captain. She takes command of the Muppet Theatre and sails it out to sea. Kermit, foolishly, declares that this is impossible. Then they raise the backdrop, and instead of the usual brick wall, there's a bowsprit and waves. The backstage sets remain the same, but rock gently back and forth with the waves.

Jackson remains in pirate character for the entire remainder of the show. Even for the Muppets, it was a high bar in surrealism and commitment to a bit.
