FYI, hands, forearm, face, head, feet, nose (some include mouth/ears/more) have to be cleaned (generally 3 times each) before going into the empty room where everyone pretends to present themselves to their silent, invisible god to declare their love and admiration for him, tell him how great he is, thank him for being so great, pledge their devotion to his invisibleness and lack of communications, etc., that kind of thing. Five times a day, every day, and also just prior to strapping on explosives to take out infidels, etc., and various other celebrations.
Brilliant, just brilliant I'll pinch that if you don't mind..
