Ru:  Oh, Piggy!  You look marvelous!
Piggy:  Of course!  Moi is always at her best when dressing for a party.
Ru:  Um, about the party, Piggy.  Look, I know we usually have some sort of birthday bash or something but--
(There is a knock at the door.)
Ru:  Um, come in.  Look, Piggy--I hope you won't be too disappointed, but--
(Kermit and Fozzie enter the room, and Kermit is momentarily transfixed, looking at Piggy in her new evening gown.)
Kermit:  Wow.  I mean, um, gosh, Piggy, you look...you look all...wow.
Piggy:  (preening a little)  Why, thank you, Mon Capitan.  Ru was kind enough to whip this little confection into being for Moi.  (Piggy turns around slowly for the full effect.)  You approve?
Kermit:  Approve?  I...wow.  You look great, Piggy.
Fozzie:  (tugging on Kermit's arm)  I'm hungry.  I thought you said there would be food.
Kermit:  What?  Oh--oh, food.  Right.  There will be.  But not here.
Fozzie: (whining just a little)  What do you mean, not here?  Ru always feeds us.
Ru:  Of course I do.  I could, um, whip up a peanut-butter and honey sandwich in a jiffy if you'd--
Kermit:  (whispering furtively)  Fozzie!  Not now!  You can't.
Fozzie:  She was going to make it.
Kermit:  No--I mean, she can't because we're all--  (He grabs Fozzie's arm, pulls him close and whispers into his fuzzy ear.)
Fozzie:  (eyes widening) Oh.  Oh!  (to Ru) Um, nevermind.  We have to, um, be somewhere--
Kermit:  Fozzie!
Fozzie:  Um, I mean, GO somewhere--
Piggy:  Fozzie!
Fozzie:  (runs nervously over to Ru and takes her hand)  Come with me.
Ru:  Um, where are we going?
Fozzie:  I'll tell you when we get there.
Ru:  But, but I'm not dressed, Fozzie.
Fozzie:  Me either, and Kermit never wears any clothes.
Ru:  Well, yes, but I have purple thread all over my pants and...(sighs)...oh, what the hey.  Lead on, my good bear.
Piggy:  (growling) Finally.  (then to Kermit)  This better not be in the laundry room this year!
Kermit:  (putting a proprietary arm around Piggy's waste)  No--of course not.  It's not in the laundry room.  (muttering)  It's in the muppet labs.
Piggy:  WHAT?
Kermit:  (hurrying her along)  Oh, look, honey--there's a taxi! 
Piggy: Kermit!
Kermit: (dives in swiftly and kisses her on the cheek)  Happy Birthday, Piggy.  (turns to Ru)  Happy birthday, Ru.  Up for some, um, exploding cake?
Ru: (laughing and shaking her head) Sounds like a plan!
Here's Piggy in her new dress that I made her for her birthday  (I like the windswept hair....):
