Cover art for Elephants lyrics by Them Crooked Vultures

I think it's about the dissident disposal system made up of informant pests, "roll over" as in snitch on someone. Elephants as in elephant in the room. Their song Keep your eyes peeled is also about this also. I might join if it didn't line up so well with the mark and image of the beast and other prophesy of ppl betraying each other and killing others thinking it's a service to God.
