Penny is a 12-minute short film about a young man who wants nothing more than to dance with the girl of his dreams. The only problem is ... he can't dance.

Donna teaches Timmy to dance, and in the background we hear two hits from the period: Rip it Up from 1956 and Great Balls of Fire from 1957.

Penny is dancing with another guy to Great Balls of Fire while Timmy shyly looks on. But then something happens... The music for the final scene is the hit song from both 1963 and 1977 Da doo ron ron. These nonsense syllables were originally intended as placeholders until lyrics for those lines could be written, but they caught on, and were kept as actual (though nonsensical) lyrics.
