John Ritter was on the show and was rather enamored with Piggy. She, however, only had eyes for George Hamilton.
Tony Clifton (Andy K.) and Piggy sang a medley of songs (I Will Survive, That Old Black Magic, etc.)
The rest of the Muppets, Kermit, Fozzie, Gonzo, Rizzo, Janice, and some others were in the production room (can't think of the right word for that place!!) and Kermit and Piggy had a fight after she threw herself at George H.
I think the funniest part is when Piggy realizes that the show is only a special and not a pilot for her own series and walks off leaving John Ritter (dressed as Piggy) to do the closing number!
But, in true Piggy style, she returns to "ham" it up!
Ouch, that pun was bad even for me!!
