B.B. King sings this song along with Big Bird, Bert, Benny Rabbit, Baby Bear and a pair of Anything Muppets. B.B. claims he's the king of B-words, hence his name. During the song, he sings about how if there were no letter B, there would be no beards (which the Anything Muppets rip off of each other) and there would be no Bert, Baby Bear, Big Bird, Benny or himself.
