The exact words that Tony accidentally turned Miss Piggy into stone with were"ZARK ZARK CHUNGLE,CLARK CLARK CHUNGLE".At the end of that episode,during the regular onstage closing scene,when Tony apologized to Kermit for what happened,Kermit asked Tony how the whole thing happened in the first place.So in explaining it to Kermit,Tony repeated the magic words,but ended up turning Kermit into stone.Linda Ronstadt guest starred in the following episode.I'm not sure how many people have noticed this other than me,but there was a rather interesting simularity between this episode and the one we just talked about.In this episode,Kermit is all dressed up in a white tuxedo,excited about meeting Linda Ronstadt.He had a crush on her.Meanwhile a huge trunk full of fungus is hauled backstage for some reason.When Miss Piggy gets word of Kermit's interest in the guest star,she fumes with jealousy and throws Kermit into the trunk and locks it.With everyone else wondering what happened to Kermit,Scooter ends up hosting the rest of the show.Linda Ronstadt comes upon the trunk,and hears Kermit calling for help inside it.So she opens up the trunk,and the two of them finally meet eachother face to face.Linda then sings"I've Got A Crush On You"to Kermit.However,when she walks upstairs to her dressing room,with Kermit still sitting in the trunk,Miss Piggy comes and shuts the trunk again.Once again everyone else is wondering what happened to Kermit.Until Miss Piggy brings the trunk with Kermit locked in it,to Pigs In Space,where Link Hogthrob and Professor Strangepork try out a zapping gun.Miss Piggy asks Kermit"Are you going to see Linda Ronstadt again?".When Kermit replies from in the trunk"Piggy that's not fair",Miss Piggy tells her two crew mates"It's zappo time"and Kermit gets zapped with the gun.Then Linda Ronstadt comes to the rescue.After Linda and Piggy talk things over,they release Kermit from the trunk.Then at the onstage closing scene,Miss Piggy is seen somehow locked up in the trunk.Do you see what I mean?In Tony Randall's episode,Miss Piggy is turned into stone throughout most of the episode,while Kermit gets turned into stone at the very end of the show.While Linda Ronstadt's episode has Kermit locked in a trunk throughout most of that show,with Miss Piggy locked in the same trunk at the end of that episode.The same basic idea,only different impression of it.
