title: Can !a!=!!b^!!-!a||!+!a|!c return anything other than 1?
body: <p>I was playing the Javascript game with somebody and we were having fun making ridiculous and absurd expressions to make our inputs get a particular output.</p>
  
  <p>This little charming one</p>
  
  <pre><code>!a!=!!b^!!-!a||!+!a|!c
  </code></pre>
  
  <p>always seemed to return <code>1</code>. I tried to reason it out, but I gave up after losing track of all the <code>!</code>s.</p>
  
  <p>Are there any values for <code>a</code>, <code>b</code>, and <code>c</code> which do not return <code>1</code>? If not, why does it always return <code>1</code>?</p>
