I ripped off this photo from The Sis, because it's just too good/insane/awe-inspiring not to share.
The mind reels at the slogans they didn't put up:
"Find a partner, form a single-file line, and prepare for an eternity of torment."
"In the event of the apocalypse, crouch under your desks and cover your heads … as if hiding will help."
"Swimming means the buddy system, people. That includes swimming in lakes of hellfire."
