Jim Henson made four 20-second commercials for Royal Crown Cola in 1966. The ads featured two Muppets, Nutty Bird and Sour Bird. Three of the ads are summarized below; the fourth ad was called "Swallow".
|Guitar|| Nutty Bird strums on a guitar.
Nutty Bird: (sings) I sing the praises of Royal Crown Cola!
Sour Bird: I hate folk singers with a message.
Nutty Bird: It is such a wow, you should buy some now!
Sour Bird: Great lyrics.
Nutty Bird: Royal Crown is its name, it's got quick-fresh energy, and you'll love RC like me!
Sour Bird: Is that the end?
Nutty Bird: There is no end to the praises I sing of Royal Crown Cola!
Sour Bird shakes his head as Nutty Bird keeps strumming.
|Thirsty|| Nutty Bird downs a bottle of RC Cola.
Sour Bird: That Nutty Bird is always drinking Royal Crown Cola.
Nutty Bird: Oh, boy! Was that great! Talk about quick-fresh energy! Wow!
Sour Bird: Hey, Nutty Bird. Why do you always drink RC Cola?
Nutty Bird: I don't always drink RC Cola. Only when I'm thirsty. But you know what?
Sour Bird: What?
Nutty Bird: I'M THIRSTY!
Nutty Bird cracks open another bottle of RC Cola, laughing hysterically.
|Rapture|| Nutty Bird rummages happily through a pile of Save-a-Seals.
Nutty Bird: Oh, these Save-a-Seals are great!
Sour Bird: The Nutty Bird there is excited because he gets a Save-a-Seal under the cap of each Royal Crown Cola, the quick-fresh energy drink.
Nutty Bird: Oh, rapture sublime!
Nutty Bird falls backwards into the heap of Save-a-Seals.
Sour Bird: Each Save-a-Seal is worth a penny. You save 'em up, and send 'em in for cash.
Nutty Bird: Look, I'm rich! RICH!
Sour Bird: How'd you get so many?
Nutty Bird holds up a bottle of RC Cola.
Nutty Bird: I drink a lot!
