“Projectors are like hymn books, except they are an average of 123,400 percent more expensive. They are used to help humans follow along with the music because their memories are very poor. The only thing worse than a human’s memory is his attention span, which the projector remedies by adding flashing lights and pictures of clouds to the worship lyrics. It’s odd that they even need this, considering the song that morning consisted of a single line sung forty-eight times. Humans are such limited creatures.”
