Philip Glass is hired by the South Park Elementary staff to conduct a play with no overt religious or traditional themes. The play is described as "the non-offensive, non-denominational holiday play". The children all wear matching green leotards and walk aimlessly about the stage.
Philip Glass plays music that has no emotional tones with a robotic voice repeating the word "happy". The parents and audience agree that it's a terrible play and proceed to get into an argument over the outcome, even though it is exactly what they had asked for.
As I turn and look into the sun, the rays burn my eyes.
Happy Happy Happy, Everybody Happy
How like a turtle the sun looks.
- For whatever reason, the "happy happy happy, everybody happy" vocals are removed from the song in the HD remaster of the episode.
