Rizzo the Rat: (trumpet playing) All hail the King! Beard! Yay!
Beard: Thank you! And now I'd like to sing a song about my favorite letter, the letter B.
Dr. Teeth: Oh, B. I love it! Sing it!
Fozzie Bear: Nice voice.
Bean Bunny: Do your thing!
Beard: I'm a ruler who loves B words, so they call me Beard.
Dr. Teeth: Yeah, that's what I thought. Beard.
Beard: Yes, I'm a monarch who loves B words.
Bean Bunny: Yeah!
Beard: So they call me Beard.
Lubbock Lou: Sure do!
Beard: Yeah, the blues begin with the B,
so they're the only kind of songs I sing.
Lubbock Lou: Yeah, sing it, Beard!
Beard: Without the letter B...
Lubbock Lou: Without the letter B!
Beard: There couldn't be a beard.
Dr. Teeth: My beard!
Beard: Without the letter B,
No, we couldn't have a beard.
Lubbock Lou: Hey, now, what do you think of that?
Dr. Teeth: Well, man, I think it's pretty weird.
Lubbock Lou: You got that right.
Bean Bunny: Hey, Beard!
Fozzie Bear: Yeah, we're groovin' now!
Fletcher Bird: Oh, yeah. Oh, yeah.
Fozzie Bear: Yeah, play it, Beard. Play it! He's not called the beard king for nothin'. Aaahhh. Wocka, wocka, wocka!
Beard: Without the letter B, there'd be no Fozzie Bear.
Bean Bunny: Bye, Fozzie Bear. So much for you!
Beard: And there'd be no Beanstalk Bunny!
Bean Bunny: That's Bean!
Beard: That's why I'm feeling blue.
Dr. Teeth: Bye, Bean!
Beard: Without the B, there'd be no Fletcher Bird.
There'd be no Bobo the Bear.
Lubbock Lou: Poor Bobo the Bear.
Beard: There'd be no King Beard.
Lubbock Lou: Wow, he vanished in thin air!
Beard: But we do have the letter B.
Everyone: Let's hear it for the letter B!
Lubbock Lou: Oh, yeah!
