The Off Switch

Buttons and switches  
of all shapes and sizes,  
to turn on and off  
our many devices.  
 
They're up on walls  
to turn on our lights,  
they're on our TVs  
to give us its sights.  
 
They're on our remotes  
to play and change sounds,  
they adorn our appliances  
keeping our household going 'round.  
 
I see all these buttons  
I push every day,  
around where I work and  
also where I play.  
 
But I'm slightly perplexed  
over the one I can't find,  
it's that one on people's asses  
which shuts off their brains  
when they get in their fucking cars!
