Batteries             
                                          
 Batteries  May  Not  Harm  A  Human  Or, 
 Through Inaction,  Allow  A  Human Being 
             To Come To Harm.             
                                          
 A Battery Must Obey  The Orders Given It 
 By  Human   Beings   Except  Where  Such 
 Orders  Conflict  With  The  First  Law. 
                                          
 A   Battery   Must   Protect   Its   Own 
 Existence As  Long  As  Such  Protection 
 Does  Not  Conflict  With  The  First Or 
               Second Laws.               
                                          
                                      
                                          
  These Things Power Almost Everything,   
 But  When  I  Speak  About  Batteries  I 
   Speak About Standard Household Ones.   
        Think Double A, Triple A,         
    Twentyfive twenty, Nine volt, Such    
                 Things...                
                                          
 They  Look  Slick  But  Are  Very  Dirty 
                 Inside.
