if ($(function () { }); is legitimate code, why isn't $(foo())?
<p>So, we should all know about the jQuery document-ready handler:</p>

<pre><code>$(function () {
  // stuff here
});
</code></pre>

<p>So basically, if the first parameter for the <code>$</code> function is a function, then we run it on document startup, right?</p>

<p>Then why won't this work?</p>

<pre><code>$(foo());
</code></pre>
