When the two hecklers learn that The Muppet Show will be "back to corrupt a whole new medium," (specifically, comic books) they respond, in their trademark fashion, with a punny retort.
“Waldorf: Why's it called a medium?
Statler: Cause it's rarely well done!”
Upon hearing this, the ambiguously gendered Whatnot appears in their box, complaining that he (or she) has been interrupted in his (or her) attempt to summon the spirit of Chief Sitting Duck and insisting that he (or she) is fully licensed by the Board of Fakirs.
Once the medium has left, Statler asks Waldorf if they have any rotten eggs so he can "strike a happy medium."
Another fortune teller, Madame Rhonda, features prominently in the "Miss Piggy's Story," the fourth issue in the mini-series.
