Fred and Barney write a song with the help of a scammer who plagiarizes Hoagy Carmichael's "Stardust". When they unwittingly play this song for Hoagy and his agent, the agent throws them out of his office, but Hoagy forgives the two and after finding a poem Barney wrote. He later puts the poem to music and invites the Flintstones and Rubbles to a special dinner where the song is performed.
