When the pigs take over The Muppet Show in episode 224], Kermit the Pig takes over as the show's host, and claims to be a frog. When guest star Cloris Leachman doesn't believe him, he ribbits for her convincingly. By the end of the show, the real Kermit has taken control of the show again -- but Kermit the Pig shows up in the closing to say goodbye to the audience. Kermit, shocked at seeing his replacement, pushes the pig offstage.
