The Muppet Show 5x5

Browsing through an old book of magic spells, Tony accidentally turns Miss Piggy into stone. He considers bringing her to a stonemason for help. Fozzie, Gonzo and Floyd crack stone jokes as Kermit and Tony try to find a spell to change her back. Of course, the show must go on, and the Piggy statue takes the stage for "Pigs in Space".
