Sit Down Shut Up: “High School Musical Musical”

The final first-run episode of the series.  Maybe it’ll get a second life eventually in eternal reruns on Adult Swim or Comedy Central or something.  Fun fact:  the song that Helen and Andrew sings after she rappels onto the stage was originally written to be “The End” by The Doors, but I guess they couldn’t get the permissions to use it.
