When watching the episode, pay close attention to the laugh track. Originally the cast was supposed to laugh when the show was funny; but muppeteer Richard Hunt was so loud they had to add the track after all!
Statler: Well, that was different.
Waldorf: Yeah, lousy...
Both: ...but different!
Lenny the Lizard: Thank you! Thank you! Welcome to another edition of "The Muppet Show". Yes it's going to be a great show because our show is starring me! There are lots more stuff--
Baskerville the Hound: Do you know what they call a dirty dog? A mud poodle!
