Cover art for The Statue Got Me High lyrics by They Might Be Giants

Unlike most mocking religious commentaries there is no point of disillusionment about the Idol worship, which leads me to belive that the narrator never managed to reach such a point, instead it just ends talking about what "they" will find. It sounds like a suicide cult. They turn on the gas or some such and as they get disoriented by it they fantasize about the aftermath of their actions.

(and I think this could easially be made to fit any form of Idol worship)
