title: Best way of returning a random boolean value
body: <p>I've been using this for some time to return either <code>true</code> or <code>false</code> when building fake seed data. Just wondering if anybody has a better, more succinct or verbose way of returning either <code>true</code> or <code>false</code>. </p>
  
  <pre><code>rand(2) == 1 ? true : false
  </code></pre>
