I think it would be hilarious if the Muppets did a little riff on their everything-always-goes-wrong theme during the ceremony and did a routine where when they unveiled the star, it ends up reading "The Moopets" Of course everyone would freak out...
Pepe: "No no no - that's supposed to read 'The Muffins', okay?"
Piggy: "This is outrageous! How hard is it to correctly spell M-I-S-S-P-I-G-G-Y?!"
Gonzo: "Hey, don't worry everyone - this happens ALL the time!"
Kermit: "This does?"
Gonzo: "Well, not really. But it did happen once before when they misspelled Arnold Schwarzenegger. Noone noticed."
Everyone would be wanting to know who's responsible/how this happened and at first the cause seems to be the fact that The Swedish Chef was in charge of contacting the printers... "Yegensmord, Ze Moopets schtar ees croonchy, ja?"
Cue The Moopets themselves to then pop up absolutely delighted with this turn of events that THEY now have their own Hollywood star. Upon the arrival of The Moopets, Celebrity Host gets suspicious, puts two and two together, inspects the star more closely and realizes the Moopets star is a fake one placed over the real Muppets star...put there by The Moopets themselves.
Miss Piggy: "If you WANTED your own star, all vous has to do was ask...HI-YAAH!!! Now you should see a whole buncha stars!"
